Do the clergy of Christendom practice what they teach?

Some do better than others. But may I make a suggestion to you.... don't take offense, none is meant.... but you may want to consider changing your avatar. I understand the desire to portray the name of the Father, but also don't forget the third commandment, "Do not take the name of the Lord in vain." In vain doesn't only mean in cursing, but also to keep it holy and not make it common. It may be used, He introduced Himself to the people, but to be used in reverence.
