"We should have the same attitude toward all of our fellow men. We must not classify people, saying, 'This one I like about so-and so I do not.' By doing so, you will have declared war on the other person and that person will not tolerate you. Even though you may not have given any outward sign of dislike by word or gesture, you have done so by your thoughts and that is enough.
We Christians have put on Christ at Holy Baptism. We have put on God, and God is love. How is it that, having become one with God at Holy Baptism, we wage war with Him? How do we wage war By our thoughts! We emit negative thoughts to our fellow men."
