I believe that in this practice it is, but that's just my belief. Aside from constitutionality, it's just not conducive to the peace of the nation to go recognizing one religion or religious sect above all others in such a blatant manner.
Look at our anti-Catholic Protestant friend on this list. I believe that if the government officially recognized Catholicism as the preferred Christian sect (especially since he doesn't even believe they are Christian), he would be offended and very mad at the government. I'm sure he would consider it a direct governmental interference in religion and be fighting against it.
Apologies to Gargantua, of course, if I am incorrect. You are entitled to your beliefs.
Indeed. As are you.
As were America's Founding Fathers, who emphatically and repeatedly insisted that America is a Christian Nation... that to stray from that truth would be to destroy our Republic.
Leave a guy on a deserted island with a Bible and he can become a Christian. But he'll never be a Catholic, Mormon, etc... Without the extraneous philosophy, the guy on the island has a better chance of getting to heaven lol.
