22 Listen to your father who gave you life,
and do not despise your mother when she is old.
23 Buy truth, and do not sell it;
buy wisdom, instruction, and understanding.
24 The father of the righteous will greatly rejoice;
he who fathers a wise son will be glad in him.
25 Let your father and mother be glad;
let her who bore you rejoice.
St Augustine of Hippo ( from Numida, North Africa) is the most important convert to Christianity, next to St. Paul. His mother Monica was a devout Christian while his father was a pagan. Monica raised Augustine as a Christian but he did not accept Christian belief or baptism.
He was educated in philosophy and rhetoric at Carthage and taught in Rome. There he converted to Christianity, was baptized, and eventually became a priest and bishop. He wrote prolifically, much of which we still have available today, including Confessions and The City of God. (source- Spiritual Classics)
