What shirt would look better for a baptism?

None of them. Go for a solid color or possibly vertical stripes such as http://www.ae.com/web/browse/product.jsp?productId...

Plaid is inappropriate for the occasion.

I think the first or fourth. I'm one who believed that denim (unless it is a dress) is not formal enough for church. I just did not like the 2nd's colors. I liked the 4th the best.

I liked the fourth one. or the first. Whichever you prefer but I don't think denim is appropriate for church and the second is too colorful. So I like the first one best but the fourth is nice too. Whichever you decide should be fine.

I think the fourth one is best depends on the rest of your outfit to be honest you don't wanna wear something to bright like yellow but don't go with black either because it might be to bland

I would go with this shirt:

You should get an l7 smell the magic tour shirt! It would look awsome!
