“I recently read an article which sought to reveal similarities in the thought of two famous philosophers, one of whom was Catholic, the other a Deist (someone who denies that God continues to act upon the created world). The author’s stated goal was to show adherents of the Deist philosopher that they could come to see how Catholic thought was, in some sense, not dissimilar from their own. Curiously, the article presented itself purely as a philosophical exercise. However, it was really an exercise in apologetics, or the practice of demonstrating the reasonableness of certain beliefs. This specific kind of apologetics seeks to allow persons to come to acknowledge the beliefs of Catholics without having to radically change their own.
Since St. Paul at the Acropolis, the Church has sought to use non-Christian thought as a starting point or instrument to preach the truth. Possibly the greatest example of this is St. Thomas’s utilization of Aristotelian thought to teach theology. However, the above-described apologetics seems to be a fundamentally different project. St. Thomas used Aristotle because he believed that Aristotle taught true things. But what about the practice of adopting a system of thought not because one considers it true, but because it can be useful? Can one rightly adopt certain philosophical tenets in order to better reach a certain audience?
In one sense, yes. We do this all the time. We discuss the Faith differently with different audiences. We try and become all things to all people. One does not begin to teach the Faith to children (unlike seminarians) by opening with a discussion of epistemology. Instead, we seek to teach in a way that people will understand, assuming the level of our audience. Beginning with truths that our audiences agree on, we can move forward in understanding and knowledge.
However, there is also a mode of apologetics that does not seem to be acceptable. This would be to accept certain things that are false and gravely harmful in order to preach the Gospel. One should not assume the tenets of a materialist (someone who denies the existence of spiritual things) in order to preach the Gospel. It would be impossible to preach the fullness of Truth while failing to affirm the existence of such fundamental things as the immateriality of God, the angels, and the soul. It is similarly difficult to hold the doctrine of the Real Presence of the Eucharist by transubstantiation without a belief in the existences of substances or the reality of the physical world outside ourselves.
In our time, many philosophical truths that the Catholic Church holds to be rationally evident, such as the ability to recognize objective moral values, are no longer held by many individuals. There can be a temptation to try and tailor the Faith to fit these understandings. After all, it seems like we could be much more popular with the culture at large if we adapted the Faith entirely to their system of thinking. However, I doubt that the end product would much resemble the Catholic Faith. While we should seek to communicate effectively, this does not mean that the content of the Faith should be sacrificed in the process.
Apologetics should be moderated by a commitment to the fullness of the Gospel, practiced with the understanding that one is trying to convert the other via arguments based upon shared principles, without sacrificing anything fundamental. We cannot sacrifice truth and still preach the fullness of Truth. Instead, we should seek to communicate, person-by-person, the person of Jesus Christ and all that this entails. Although this takes on different modes, the goal remains the same. While we may wish to find common ground with all different sorts of groups in order to maintain a certain standing in society, certain truths cannot be abandoned for the sake of popularity. After all, the Faith is not even ours to begin with. So, is comparing systems of thought a true mode of preaching? Possibly (leaving aside questions of its limited effectiveness), but only under specific constraints and with the recognition that this form of apologetics must be guided by a special concern to maintain the Faith that has been handed on to us.

Summa Catechetica, "Neque enim quaero intelligere ut credam, sed credo ut intelligam." – St Anselm, "“Si comprehendus, non est Deus.” -St Augustine, "Let your religion be less of a theory, and more of a love affair." -G.K. Chesterton, “When we pray we speak to God; but when we read, God speaks to us.” -St Jerome, "As the reading of bad books fills the mind with worldly and poisonous sentiments; so, on the other hand, the reading of pious works fills the soul with holy thoughts and good desires." -St. Alphonsus Liguori, "And above all, be on your guard not to want to get anything done by force, because God has given free will to everyone and wants to force no one, but only proposes, invites and counsels." –St. Angela Merici, “Yet such are the pity and compassion of this Lord of ours, so desirous is He that we should seek Him and enjoy His company, that in one way or another He never ceases calling us to Him . . . God here speaks to souls through words uttered by pious people, by sermons or good books, and in many other such ways.” —St. Teresa of Avila, "I want a laity, not arrogant, not rash in speech, not disputatious, but men and women who know their religion, who enter into it, who know just where they stand, who know what they hold and what they do not, and who know their creed so well that they can give an account of it, who know so much of history that they can defend it. I want an intelligent, well-instructed laity… I wish you to enlarge your knowledge, to cultivate your reason, to get an insight into the relation of truth to truth, to learn to view things as they are, to understand how faith and reason stand to each other, what are the bases and principles of Catholicism, and where lie the main inconsistences and absurdities of the Protestant theory.” (St. John Henry Newman, “Duties of Catholics Towards the Protestant View,” Lectures on the Present Position of Catholics in England), "We cannot always have access to a spiritual Father for counsel in our actions and in our doubts, but reading will abundantly supply his place by giving us directions to escape the illusions of the devil and of our own self-love, and at the same time to submit to the divine will.” —St. Alphonsus Ligouri, "The harm that comes to souls from the lack of reading holy books makes me shudder . . . What power spiritual reading has to lead to a change of course, and to make even worldly people enter into the way of perfection." –St. Padre Pio, "Screens may grab our attention, but books change our lives!" – Word on Fire, "Reading has made many saints!" -St Josemaría Escrivá, "Do you pray? You speak to the Bridegroom. Do you read? He speaks to you." —St. Jerome, from his Letter 22 to Eustochium, "Encounter, not confrontation; attraction, not promotion; dialogue, not debate." -cf Pope Francis, "God here speaks to souls through…good books“ – St Teresa of Avila, Interior Castle, "You will not see anyone who is really striving after his advancement who is not given to spiritual reading. And as to him who neglects it, the fact will soon be observed by his progress.” -St Athanasius, "To convert someone, go and take them by the hand and guide them." -St Thomas Aquinas, OP. 1 saint ruins ALL the cynicism in Hell & on Earth. “When we pray we talk to God; when we read God talks to us…All spiritual growth comes from reading and reflection.” -St Isidore of Seville, “Also in some meditations today I earnestly asked our Lord to watch over my compositions that they might do me no harm through the enmity or imprudence of any man or my own; that He would have them as His own and employ or not employ them as He should see fit. And this I believe is heard.” -GM Hopkins, SJ, "Only God knows the good that can come about by reading one good Catholic book." — St. John Bosco, "Why don't you try explaining it to them?" – cf St Peter Canisius, SJ, Doctor of the Church, Doctor of the Catechism, "Already I was coming to appreciate that often apologetics consists of offering theological eye glasses of varying prescriptions to an inquirer. Only one prescription will give him clear sight; all the others will give him at best indistinct sight. What you want him to see—some particular truth of the Faith—will remain fuzzy to him until you come across theological eye glasses that precisely compensate for his particular defect of vision." -Karl Keating, "The more perfectly we know God, the more perfectly we love Him." -St Thomas Aquinas, OP, ST, I-II,67,6 ad 3, “But always when I was without a book, my soul would at once become disturbed, and my thoughts wandered." —St. Teresa of Avila, "Let those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me." –St. Augustine, "Without good books and spiritual reading, it will be morally impossible to save our souls." —St. Alphonsus Liguori "Never read books you aren't sure about. . . even supposing that these bad books are very well written from a literary point of view. Let me ask you this: Would you drink something you knew was poisoned just because it was offered to you in a golden cup?" -St. John Bosco " To teach in order to lead others to faith is the task of every preacher and of each believer." —St. Thomas Aquinas, OP. "Prayer purifies us, reading instructs us. Both are good when both are possible. Otherwise, prayer is better than reading." –St. Isidore of Seville “The aid of spiritual books is for you a necessity.… You, who are in the midst of battle, must protect yourself with the buckler of holy thoughts drawn from good books.” -St. John Chrysostom
