“The light of the Trinity illuminates everything…We can think about the Trinity in two basic ways. First, we can start with our concrete, personal, affective relationship to God Whom we encounter and know in the faith as Father, Son, and Holy Spirit. This is an interpersonal knowledge of “I and Thou.” We might call this “intuitive second-person knowledge” of the mystery of God, as when we say to God: “You, Almighty Father, have revealed yourself to me in Christ.” “Oh Holy Spirit of Christ, enlighten and sanctify us!” Second, we can focus on our speculative understanding of God as we consider the mystery theologically. How do we analyze the mystery of Father, Son, and Spirit as the one God?
These two pathways of affective knowledge and intellectual theory are distinct but not separable. In fact, they are deeply interrelated to one another. Consider an analogy to human relationships. It is one thing to come to know another person well in friendship, and another thing to reflect philosophically on the nature of human friendship. The relational, affective knowledge is primary because it is the lived experience of friendship which is irreplaceable, but our own theoretical understanding of friendship not only allows us to analyze what friendship really is, but also can help us live out friendship more perfectly. Heart and intelligence go together. So likewise with the Trinity, supernatural faith alerts us to the real presence of the Father, manifest in the Son made man, and to the gift of the Holy Spirit present in the Church, Who dwells in our hearts by grace. This is a mystical reality that is primary, and is simply given to us to know by grace. We can become more and more aware of it over time through the deepening of our life of faith, interior prayer, and religious worship. However, knowing the Trinity personally, in the darkness of faith, we are also invited into the active consideration of the mystery, the intellectual reflection of theology.
The great works of reflection on the Trinity in the early Church—those of Irenaeus, Gregory of Nazianzus, Augustine, and others—are living meditations that spring from the inner life of faith, and from reflection on scripture and Church doctrine. They are profound intellectual works, but they are also grounded in a deeper mystical life and spiritual aspiration. Gregory and Augustine were trying to find union with God. The idea of study here is not a mere academic exercise. It allows us to grasp better Who it is that we know in the faith and What we worship, to understand how this highest mystery of the faith illumines all other knowledge and understanding of the created world.
…For the Christian faith, knowledge cannot be separated from love and is always related to it integrally. As Aquinas says, “formed” faith is faith enlivened by charity, without which our faith (perhaps even very intellectually erudite and nuanced) is dead or lifeless.2 At the same time, we have to insist that theology looks at questions of truth that have an integrity of their own, that are not reducible to the piety and emotional life of believers. Love without a transparent sense of responsibility to the truth usually degrades into sentiment, delusion, or cultural nostalgia. If theology is prayerful and spiritual, it is also probing, analytic, and rigorous in its own right. Theology has to be subject to real challenges and engagements with its external critics as well as with its own deepest internal intellectual struggles and enigmas. Thinking about the Trinity, then, is a spiritual exercise, but it is also a speculative one, and it is above all a search to find the fullness of the truth about God, unabated light free from all error. This search for the unalloyed truth is also itself a very profound element within the spiritual life. After all, Christ Himself claims to be “the truth” Who alone “will make you free.”3 The search for the God of Christianity is a search for the fullness of the truth. Otherwise it has no real purpose.”

Summa Catechetica, "Neque enim quaero intelligere ut credam, sed credo ut intelligam." – St Anselm, "Let your religion be less of a theory, and more of a love affair." -G.K. Chesterton, "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, "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."- Bl John Henry Newman, Cong. Orat., "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
