When did Christians ever keep it to themselves?
I would go so far as to say that a Christian who keeps his or her religious views to him- or herself is barely a Christian anymore. We all know that some Bible passages contradict others to the point that some selection is necessary, but no passage seems to have been anywhere nearly as consistently and tenaciously followed as the last 3 verses of Matthew. I'm talking about Matthew 28:18-20:
18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
Amen, indeed! Hallelujah, good night and pass the ammo! Of course, because of the necessary selection which I just mentioned, what they teach will vary wildy, but the missionary spirit has been remarkably consistent for the last 1950 years or so.
But yeah, sure, that's the past! To paraphrase Sam Kinison, just because you lied to me the last 9 times, why would would anyone expect ya to lie to me 10 FUCKING TIMES IN A ROW?! YAAARGGHH!! Why would anyone expect things to go on as they have in the past for thousands of years without a pause? "Okay, Mr Tiger, we're going to put you into this enclosure with all these lambs and calves and little baby ducks and piglets -- as long as you promise not to hurt any of them! You promise? Okay then! What could possibly go wrong?"
