Christ to the Other

"Just as our neighbor is in need and lacks that in which we abound, so we also have been in need before God and have lacked His mercy. Hence, as our heavenly Father has in Christ freely come to our help, we also ought freely to help our neighbor through our body and its works, and each should become as it were a Christ to the other, that we may be Christs to one another and Christ may be the same in all; that is, that we may be truly Christians."
