The Faith of Christians

The closest we get in all of the Bible to a definition of faith is the famous summation in the Epistle to the Hebrews, “Faith is the realization of what is hoped for, and evidence of things not seen.” In the middle ages, there was considerable debate as to whether this statement amounted to a definition or not. St. Thomas Aquinas devotes a special article in his Summa to this question.

Aquinas concludes that, although the definition is not in correct syllogistic form, it amounts to an “informal” definition. He then goes on to reformulate this passage as a more properly formal definition: “Faith is the habit of the mind, by which eternal life begins within us, causing the intellect to assent to that which has not yet appeared.”

Aquinas brings together the subjective and objective connotations of hypostasis – faith is a habit, or virtue, of the mind, and also the seminal implantation of eternal life. And though oriented toward an unseen “homeland,” it brings about the same type of assent or conviction generated by objective realities encountered here and now. In other words, it is the grounding in our present life for our entry into eternal life, and supplies the believer with evidence for the existence of a transcendent realm.

This definition is obviously paradoxical. It is experiential, but not in any ordinary sense of experience. It refers to an experience of being able to go beyond experience. The “substance” or substantial “realization” that the author of Hebrews refers to is, to utilize more philosophical language, a power or “potency” that complements the natural capabilities of the believer. The paradoxical experience that results is an encounter with the “evidence” for the unseen mysteries to which faith is directed.

A Christian thinks of the Apostles and disciples after Pentecost, traveling out into the then-known world to spread the “good news.” Many of them – having known Christ, seen his works, witnessed his resurrection, received empowerment from the Spirit – were similar to a reporter who had just come upon a scoop, and was impatient to spread the news; or, perhaps more appropriately, like the woman (Luke 15:8-9) who finds a lost coin she had been searching for, and goes out proclaiming her good fortune to all her neighbors.

For many of the first Christians, the primary source of their faith was preaching, by Christ himself, or by John the Baptist. St. Paul points to the ordinary source for the activation of faith:

Whosoever shall call upon the name of the Lord shall be saved. How then shall they call on him in whom they have not believed? and how shall they believe in him whom they have not heard? and how shall they hear without a preacher?

But obstacles stand in the way, as Christ points out in his parable of the sower with the seed:

The seed is the word of God. Those on the path are the ones who have heard, but the devil comes and takes away the word from their hearts that they may not believe and be saved.

What other sources are available for eliciting faith? Christ offers one alternative source. Those who don’t believe his words may be convinced by his “works,” i.e., the “signs” that he offers; and the disciples that he is sending out to spread the announcement of the coming of the Kingdom will also be distinguished and recognized by their “signs” – casting out demons, speaking new languages, healing the sick, etc. To these signs, Paul adds the gift of prophecy and the gift of tongues (the “glossalalia”).

The signs that were almost exclusively offered by Christ himself were exorcisms of evil spirits and miraculous healings. One may presume that it was primarily signs, rather than preaching or Scripture, that elicited the faith of the Caananite woman who asked Jesus for the “leftovers” after he had accommodated the Jews, and the faith of the Roman centurion who sent a messenger to ask Jesus for a cure of his servant.

Are miraculous “signs” still given to bolster faith? There are occasionally “private revelations,” or miraculous healings at shrines like that in Lourdes, where teams of doctors examine cases of alleged cures after bathing in the spring; or through the ministration of exceptional individuals such as St. Padre Pio of Pietrelcina (1910-1968), by whose intercession numerous inexplicable healings were reported; or to occasional public miracles witnessed by tens of thousands – such as the miracle of the sun at Fatima in 1917, or the publicly witnessed, videotaped, and governmentally investigated apparitions of the Virgin Mary in Zeitun, Egypt, in 1968 and 1969.

Skepticism about miracles is common now, even among Christian theologians, to whom a miracle seems an unwarranted and unnecessary intervention by God in the very laws of nature. Some believers seem to think that they don’t “need” miracles to bolster their faith. The often unappreciated source for this view is to be found in the anti-Christian sentiment of the eighteenth-century Enlightenment.

As Frank Tipler observes: “The idea that a miracle violates the laws of physics was introduced in the English-speaking world by the Deists, whose motivation was to deny the Resurrection and the Incarnation. If a miracle violated physical law, if the Resurrection and the Incarnation violated physical law, then the Deists could use the strong evidence that physical laws were never violated as evidence against the Resurrection and Incarnation. Hume [in his treatise on miracles] just continued and expanded this Deist strategy.”

“Saint Paul Preaching on the Areopagus” by Leonard Porter,
“Saint Paul Preaching on the Areopagus” by Leonard Porter,

In any case, signs are not a sine qua non for one’s faith. Jesus even warned about depending too much on signs.

What, then, are the major sources of faith now – sources that may inspire the sort of enthusiasm reported among the first Christians? Have they changed? Theoretically, technology is so advanced now that the Gospel, as “Good News,” could be proclaimed worldwide with the use of radio, satellite television, the internet, social media, etc.

But the practical obstacles in the way of this communication seem insuperable. How can the message of the Gospel be communicated to aborigines, the illiterate, the isolated? to individuals in dictatorial regimes prohibiting free speech; to individuals in religious sects which distort and vitiate the word of God, and/or spread violent sectarian rivalries, and/or use force to prevent hearing of the Word; or to secularists surrounded by family, friends, colleagues, and a culture that has imbibed the alternative “good news” (namely, that science has all the answers, and scientific orthodoxy should be the litmus test for beliefs?) How can the Gospel be conveyed to those in progressive, industrialized societies who are just too busy to listen?

Scriptures and preaching are still major sources. But it may be a mistake to put too much emphasis on Scriptures and preaching. Other sources may be more effective for some persons. For instance, the investigation of nature, if not the major source of faith, is certainly an important auxiliary source in all eras, since, “Ever since the creation of the world, God’s invisible attributes of eternal power and divinity have been able to be understood and perceived in what he has made.”

In the contemporary world, with the exponential growth of scientific knowledge, this source may be more important than it has ever been in the past. As St. Paul mentions, the basic prerequisite for faith is that one comes to believe that God exists, and that He rewards those who seek him; and contemplation of Nature seems to be a path to faith taken by many in the scientific community. Awareness of a Designer can be a starting point for transition to a belief in divine providence and eternal life.

Faith is described by St. Paul as an indistinct vision of the divine: “At present we see indistinctly, as in a mirror, but then face to face. At present I know partially; then I shall know fully, as I am fully known.” There are a variety of “mirrors” in which we see may see partial reflections of God. Signs of divinity and power and creativity can be seen in nature, as St. Paul notes, unless by some strange cerebral gyrations a hyper-enlightened individual perceives in nature only the incredible workings of Chance as a substitute for divinity.

Since humans are made in the image of God, more or less distinct visions of divine love, wisdom and power are available in our neighbors, unless we habitually view them with the glasses of indifference or hate. And a Christian who meditates on the life and deeds of Jesus will come to see evidence of divinity.

Although doubt is compatible with a search for the proper objects of faith, the indistinct vision of the divine that comes through the “mirror reflections” of faith can be free from doubt, just as while looking at a reflection of someone we may lament the fuzziness or cloudiness of the image, but have no doubts about who is being represented.

Another characteristic of faith is an openness to divine power. In the Gospels, those who are seeking a miraculous healing are admonished to “have faith” as a prerequisite for the healing to take place. Such openness can also be a continual, habitual state, an abandonment to divine providence, which manifests itself particularly at times when human assistance is out of the question, or when believers voluntarily divest themselves from ordinary sustenance.

The Yogi, Paramahansa Yogananda, in his autobiography describes a stage in his development when he and a companion, with the support of their spiritual director, undertook a journey with no money and without begging, to solidify their faith in divine providence. As a somewhat analogous test of faith, students preparing for the Catholic priesthood in the Jesuit Order will often be sent to travel without funding, depending on the kindness of strangers or opportunities for employment that come their way.

Besides such passive openness to God’s power, faith may take the form of an openness to participating actively in manifestations of divine power. The most dramatic reference to this is the rather stunning assurance Jesus offers to his followers: “Amen, I say to you, if you have faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”

Commentators on Scripture from the earliest times have almost always taken this as metaphorical, as a reference to the great things that can be accomplished in God’s service, depending on the degree of one’s faith. But St. Gregory Thaumaturgus (“wonder worker”) is said to have moved a mountain in the 3rd century to make room for a church. And in the Orthodox Christian tradition, there are instances in which the saying was taken literally. A 4th century Orthodox saint, Venerable Mark the Anchorite of Athens, is reputed to have moved a mountain into the sea. And in the Egyptian Coptic Orthodox hagiography, Saint Simon the Tanner in the 10th century, taunted by a challenge from the Muslim Caliph Al Muizz, is said to have moved the Mokattam Mountain as testimony to the superiority of Christianity over Islam. Needless to say, if such powerful manifestations of faith were available in our day, the choice of a religion for some seekers would be unproblematic.

Finally, faith is manifested actively in courageous perseverance in the face of death and against the forces of evil, as exemplified in Jesus’ words to Simon Peter: “Simon, Simon, behold Satan has demanded to sift all of you like wheat, but I have prayed that your own faith may not fail; and once you have turned back, you must strengthen your brothers.”

The ultimate manifestation of the strengthening caused by faith is, of course, the unflinching courage and patience of martyrs enduring extraordinary sufferings at the hands of opponents of the faith. And given conditions in our day, that type of witness is widespread in the Middle East, but may be coming closer and closer to us all.

    I wish Mark the Anchorite were around today so he could move Obama out of the White House. Now that would be a true miracle. But seriously, Howard, I appreciate this column because faith has always been the biggest stumbling block in my lifelong effort to embrace Christianity, Love and Hope I get, but Faith is elusive because is inherently requires trust on behalf of the would-be believer.

    If I take a job, for example, and my new boss promises to pay me on the last day of every month, I have to have faith that he will do so. When that day comes and I don’t get paid then faith becomes a mockery. Augustine said, “Faith is to believe what you do not see; the reward of this faith is to see what you believe.” The “reward” in this case is a paycheck. The boss will then think up some excuse and promise to deliver the next month but again fails to do so. The worker keeps toiling without pay until sooner or later he quits his job because the employer didn’t pay him. The worker loses faith every time he starts a new job and fails to see a reward.

    As long as you mentioned Aquinas, he said, “To one who has faith, no explanation is necessary. To one without faith, no explanation is possible.”

    It’s a good quote and a good out but not satisfying.

      Grump, I think the important thing to remember about faith is that it is a type of evidence, not just peering in the dark. It’s an unusual experience, not necessarily mystical, but real. Worth praying for, if you don’t have it.
      Your quote, “To one who has faith, no explanation….” is not from Aquinas, but from Franz Werfel in his book, The Song of Bernadette. I use it at the beginning of my book, and I discuss exceptions to Werfel’s generalization.

    • Paul Vander Voort

      Very interesting example. I also struggled with faith. What reward do you expect for your faith in this world?

  • monica

    Faith is a gift from God. I have no doubt that I have received this gift through the prayer and sacrifice of others who have offered for me. Some knew me and others simply offered for unbelievers. This is what builds up the Treasury of the Church. We strengthen the Faith of those persecuted Christians in the same way — prayer and personal sacrifice. Doesn’t anybody believe this stuff anymore? I was baptized as an infant, and the merits of those who went before me joined to the infinite merit of Jesus on the Cross are what brought me to the font. Now my prayers and sacrifices are helping others. We must not fail them — we must offer for others.

    .A technique which I have begun to use relies on more concrete examples. I start with the fact that Roman Catholicism is the True Church containing the True Faith. As such, It is protected by the Trinity Itself from teaching error. This approach began with the 2014 Synod on the Family and its aftermath. I simply assured people that the Magisterium, one of the Three Fonts which teach and protect the Faithful (the other two being Sacred Scripture and Sacred Tradition) will NOT allow error to be taught.
    I am cautioned that we must wait until October, 2015 to see how these questions introduced in 2014 will be resolved.
    Fortunately, we have an immediate example: for months the world and the Church have waited for the release of Pope Francis’ encyclical on the ENVIRONMENT which was imminent. However, this document it was announced will be delayed as the Congregation of the Doctrine of the Faith has told the Vatican IT WILL NOT ALLOW THIS DOCUMENT TO BE ISSUED IN ITS PRESENT FORM. Is the CDF giving orders to the Pope? No, it is the Holy Ghost intervening to protect the Church from error.

    I say to anyone that no other religion, including the 40,000 christian sects, provides this protection to Its members. Pray for the GIFT of the Faith as it the starting point of the quest for salvation.
