Catena Aurea · Lukasevangelium 14
And there went great multitudes with him: and he turned, and said unto them, If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. And whosoever doth not bear his cross, and come after me, cannot be my disciple.
(in Hom. 37. in Ev.) Or because the cross is so called from torturing. In two ways we bear our Lord’s cross, either when by abstinence we afflict our bodies, or when through compassion of our neighbour we think all his necessities our own. But because some exercise abstinence of the flesh not for God’s sake but for vain-glory, and shew compassion, not spiritually but carnally, it is rightly added, And, cometh after me. For to bear His cross and come after the Lord, is to use abstinence of the flesh, or compassion to our neighbour, from the desire of an eternal gain.
