"Attending church" is an odd way to get at the subject of public worship. If you change the question to gathering for worship I think it changes the whole conversation. Christianity is clearly meant to be communal. The notion of a single Christian who does not seek fellowship with others is foreign to the clear witness of Jesus and the early church. I have always liked the story of the woman at the well where Jesus speaks of the "day" that is "coming and now is" where worship is not location defined but spiritually defined and tested by truth. That is, "in spirit and in truth."

Sunday is okay with me, but it could also be Tuesday.
