This radical demand to love one's enemies includes sharing one's possessions with them; for Jesus says, “give to EVERYONE who begs from you” and “do not demand back from the person who takes them.” With this in mind, Luke brings in the ‘golden rule’ as the jewel in the crown to this teaching on the love of enemies. The disciples are to “do to others as they would love others to do unto them.”
As long as there is a Church, it will teach objective truth, and objective truth requires objective leadership. And that objective leadership, symbolized in the Chair of St. Peter, is directed toward unity.
