Actually since my dad is pastor this what he tells me. Church is Gods House where you praise and worship him and you dont need to go to church only on Sundays...heck hardcore christians like my dad and alot of other people go Wed. Tues. and Sat or we gather a group of Christians and meet on a certain days of a week to praise and worship. We goto church to praise and to worship God on his Resting day and since some people are really busy the best time for those people is on Sundays. Um Muslims they worship alot but your not into the real christians. Alot of christians just dont meet on Sundays we meet like Wed and Fri or even Sat not just Sundays.
