 The Christian faith is like that, something which we received from our forefathers, and which we must pass on to our children. E. F. Brown quotes a famous passage from St. Vincent of Lerins: "What is meant by the deposit? (paratheke, G3866) . That which is committed to thee, not that which is invented by thee; that which thou hast received, not that which thou hast devised; a thing not of wit, but of learning; not of private assumption, but of public tradition; a thing brought to thee, not brought forth of thee; wherein thou must not be an author, but a keeper; not a leader, but a follower. Keep the deposit. Preserve the talent of the Catholic faith safe and undiminished; let that which is committed to thee remain with thee, and that deliver. Thou hast received gold, render gold."
