No:
We already have a Christianity subforum, so you're already recognized on this site.
As posted earlier, just get a picture of a small one(like the one in the first post) and just use the Img code. Little more effort on your part, but there's no way to implement a single Religious symbol into an Emote system without having to implement them all, without having more people complaining about their religion being left out, or it insulting their religion and so forth along those lines.
For such a small idea to be added, you'd be giving Paul possibly dozens of seperate Emote's that he would have to add as well. it's just not needed, especially since you've already found a picture link that works for you. Save it somewhere and use it the long way. It'd take a lot less effort than having Paul add in dozens of new ones to make everyone happy.
Tl;dr: Too much effort for something that won't make the site be used any easier.
