23 As for those who possess not the gifts of fortune, they are taught by the Church that in God's sight poverty is no disgrace, and that there is nothing to be ashamed of in earning their bread by labor. This is enforced by what we see in Christ Himself, who, "whereas He was rich, for our sakes became poor";(18) and who, being the Son of God, and God Himself, chose to seem and to be considered the son of a carpenter - nay, did not disdain to spend a great part of His life as a carpenter Himself. "Is not this the carpenter, the son of Mary?"(19)
