Except for clothing items for cultural representation, none of the religions are really represented, and with all the players world wide, it would be hard to do that fairly. The Sims is trying to remain secular in order to be fair to players of all faiths. Christian holidays are represented only by The Sims version of their secular aspects (Easter Bunny/Flower Bunny, Santa Claus/Father Winter, Holiday Trees, Eggs, presents and crackers) and there are holiday items in BB to provide culturally relevant decorations for things like Hanukkah and Chinese New Year, but there aren’t any churches or houses of worship in the worlds, no religious symbols, and no religious activity. I’m okay with that, because when you get faith elements wrong, it can really go bad. I add churches to worlds when I want, and use the club system to create a congregation when needed. I’d rather define my Sims faith than have a development team get it wrong. I do agree that adding more BB items for a variety of faiths would be acceptable, especially if those items are relevant to a larger cultural identity.
