As mentioned in another question, I'm thinking of visiting a mosque on Wednesday around 7:50pm. I would like to participate in the Salat, because I believe that it is a beautiful and valid form of prayer directed to the true God (although many Christians would disagree with me on this point).
However I don't believe that there is any special significance in praying towards Mecca and I would feel more comfortable praying towards a tabernacle, a Eucharistic host, liturgical east, or nowhere in particular.
Seeing as I don't believe that God has any special presence in the Kaaba at Mecca, would it be inappropriate for me to participate in the Salat (towards Mecca)? Note, I'm not denying it, I just don't explicitly believe it, I'm unconvinced and leaning towards disbelief, but I don't actually reject the idea outright: it might be true!
I hope it's not an issue, because I've done Salat before and it was great. Such a wonderful way to worship God and I wish that Catholics would do it too. But if it's inappropriate because I don't share belief that God is present in Mecca, I will refrain in future
Edit: I'll note that I do believe God is present in the Kabaa, but only in the sense that God is present everywhere and in everything (omnipresence). So there's nothing particularly special about mecca: God IS there, but he's also everywhere else.
