St. John Chrysostom

Every where, beloved, we have need of faith, faith the mother of blessings, the medicine of salvation; and without this it is impossible to possess any one of the great doctrines. Without this, men are like to those who attempt to cross the open sea without a ship, who for a little way hold out by swimming, using both hands and feet, but when they have advanced farther, are quickly swamped by the waves; in like manner they who use their own reasonings, before they have learnt any thing, suffer shipwreck; as also Paul says, Who concerning faith have made shipwreck. - St. John Chrysostom
