The letters in the picture are part of the word "Peace". It has nothing whatsoever to do with the post at hand.
Love the sinner, hate the sin.
Who said that?
Some people reckon it was Gandhi and they are right, he did say it, however...
...a good 1600 years before Gandhi, Augustine said it in his book, "The City of God", book 14, chapter 6
(read the whole quote below - it unpacks it well).
...Wherefore the man who lives according to God, and not according to man, ought to be a lover of good, and therefore a hater of evil. And since no one is evil by nature, but whoever is evil is evil by vice, he who lives according to God ought to cherish towards evil men a perfect hatred, so that he shall neither hate the man because of his vice, nor love the vice because of the man, but hate the vice and love the man. For the vice being cursed, all that ought to be loved, and nothing that ought to be hated, will remain.
Moreover, what I have now said in regard to abstaining from wanton looks should be carefully observed, with due love for the persons and hatred of the sin, in observing, forbidding, reporting, proving, and punishing of all other faults.
Just in case you wanted to know.
