Augustine of Hippo, Saint (354–430)
Born Aurelius Augustinus at Thagaste in Roman North Africa (today's Algeria) of a pagan father and Christian mother, Saint Augustine of Hippo was formally educated as a rhetorician, but sought pagan, Manichaean, and Neoplatonic answers to questions about reality. After his conversion to Christianity, he became a monk, and in the year 396 was appointed bishop of Hippo Regius in North Africa. He wrote sermons, devotions, prayers, letters, polemical writings (against Manichaeans, Donatists, and Pelagians), and doctrinal treatises (e.g., On Christian Doctrine and On the Trinity). He is best known for his autobiography of his conversion, The Confessions, and his apologetic of divine providence, The City of God

Saint Augustine, 1480, fresco, Ognissanti, Florence: Saint Augustine of Hippo is regarded as one of the great fathers of the early Christian church. He was converted to Christianity in 386 and became the bishop of Hippo, in North Africa, in 396
Augustine helped to develop the Christian view of time, particularly in the following writings: On Music, The Immortality of the Soul, The Literal Meaning of Genesis, and chiefly in The Confessions, his account of his early life up to his conversion to Catholic Christianity and his decision to enter service to the church. The first ten books contain this story, and the final three contemplate God and Creation. In Book 11, amid a discussion on the creation of the cosmos, Saint Augustine enters into a meditation on time. The bishop of Hippo does not give us a scholastic argument, but in humility, an extended prayer and dialogue on time and eternity, in which he asks God to reveal to him the mystery of time, “this most intricate enigma.”
Saint Augustine first asks about God in relationship to time. He notes that God is eternal and changeless and, as time means change, then time is not eternity. Time is a creature, a creation of God; thus God is exempt from the relation of time. Eternity is fixed and time is never fixed: “No time is all at once present.” Before creation, there was no time—no past and no future: “Before all times God is: neither in any time was time not.”
Next, Augustine discusses humanity in relation to time: for Saint Augustine, it is always present and never past or future. Using images of time, motion, age, and words, he discusses the extent of the present and our perception of intervals of time. Although we recognize a past in memories (as in our childhood) and future (as in contemplating our next action), they are not present. He then proposes three categories of time: “a present of things past, a present of things present, and a present of things future,” all perceived by memory (present past), sight (present present), and expectation (present future).
After addressing humanity in relation to time, Saint Augustine discusses the measurement of time. Humans measure time in space, in that we perceive time as an extension or distention a stretching of our humanness. Yet not only do humans measure time as a movement in space but we also measure time even when things are standing still. So time, then, is not the motion of a body. Time is measured by long time and short time, “a protraction,” though we do not measure the past, present, and future. It is in the human mind that times are measured in proportion as they pass by in short or long. So, the human mind expects, considers, and remembers time: “that is that which it expects, through that which it considers, passes into that which it remembers.”
