A "Q AND A" THAT I FOUND AT CATHOLIC ANSWERS TODAY...NEVER HEARD OF IT BEFORE...

QUESTION:Why do some catholics kiss their fist after they do the sign of the cross?

ANSWER:Hi.Even though they seem to be just kissing their fist, they are actually kissing a cross they make by placing their thumb perpendicularly across their index finger.
