erm i remember reading one hadith where one sahaba found a sample of Toraat and Prophet PBUH disliked the act of him reading it.
I wouldnt mind visiting a church if the intentions are to know their belief which would help me understand my religion better otherwise my own religion is complete enough to teach me “good”.My religious concepts are enough messed up by our own scholars that i dont need to listen to their sermons to further mess them up.=]
