Mardel has a Christian education section on their website. http://www.mardel.com/education/christian-education.aspx
Oriental Trading Company often has religious items, but I don't know if they have individual classroom decor items.
What age groups? I have seen stuff, it is often labeled as VBS or Vacation Bible School. Mardel is a great resource though!

Just remember with religious stuff that there are some differences in Christian religions such as the 10 Commandments. Some of the stuff sold on oriental trading doesn't have the Catholic 10 Commandments on them. I never even thought about stuff like that until someone pointed it out in the review of a product.
Right. You can't just buy generic Christian products for a Catholic classroom. That's why I looked for specifically Catholic resources.
Oriental Trading has religious things, not specifically Catholic. I bought a lot of stuff through them, just be careful if it's anything with the Our Father because they always have the Protestant version. Depends on where you live to. There's no religious things in the teacher store near me but when I visit the one in Myrtle Beach every summer they have a lot of religious stuff.
Not sure specifically Catholic but Miller Sch. Supply does carry some Christian BB sets, incentive charts, stickers, posters, etc.
If you are still looking I bought this for my Catholic classroom http://www.teachercreated.com/produ...in-board-display-set-7037?lt=search.9.11.1.30
