This may seem like a strange question (above), given that this is an Ecclesiocentristic blogsite.
The answer to the question posed in the heading is, "It depends."
It is never sinful to go to a properly-constituted church service on Sunday, since this is the Lord's Day, the New Covenant Sabbath.
But it could very well be sinful to go to church during the week. First of all, God never commanded that there be church services during the week; and secondly, going to them could definitely be sinful.
"How?", you might be asking. One way is that by going to non-Sabbath church services, a person could well be skirting his clearly and truly God-ordained duties--as a husband, a father, an employee, a neighbor, or a citizen. Sometimes people seek to assuage their guilt by "out-Godding" God, through doing things that are patently religious (but never commanded by the Lord).
If people would simply do what God *does* command, like go to His worship, in church, on Sunday, they would be a whole lot better off.
God is never impressed by "hyper-religion." He prefers simple and sincere faithfulness over all forms of fanaticism.
The Forum for Ecclesiocentricity is designed to educate Christians and non-Christians alike to understand the Biblical teaching concerning the Church (the "Puritan" church in particular), with regard to its principal role on the earth. When this is achieved, it is hoped that the Church would then be in a better position to convey Christ's redemptive virtues to the civil government (state), and the family.
