Roman Catechism 27.11

Chapter 27 — Part III: The Decalogue — The Fourth Commandment

Section 11. To outstep these limits by loving our neighbour as we love God would be an enormous crime. If any man come to me, says the Lord 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. In the same way, to one who would first attend the burial of his father, and then follow Christ, it was said: Let the dead bury their dead; and the same lesson is more clearly conveyed in St. Matthew: He that loveth father or mother more than me, is not worthy of me.
