Why? Jesus, Himself, instructed His followers to protect themselves when He encouraged them to sell their outer garments in order to buy a sword (Luke 22:36-38; cf. 2 Corinthians 11:26-27 – a plain reading of the passage indicates that Jesus approved of self-defense). Here the “sword” (Greek: maxairan) is a dagger or short sword that belonged to the Jewish traveler’s equipment as protection against robbers and wild animals. Pretty much the equilavent of what a handgun is today.
Who said anything about two? Of course, if he did carry two (or three), I wouldn’t see that as a problem either.
He carries it in case he or his congregation is attacked as has already been the case in some churches. I think that is very prudent of him. He is taking very seriously his responsibility as a Catholic to protect himself and other innocent individuals from harm as we all are instructed to do in the CCC.
Why?
"… fear ye not them that kill the body, and are not able to kill the soul: but rather fear him that can destroy both soul and body …" Matthew 10:28.
