Religion is of God not man. The Bible says

James 1:26  If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain.

27 Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.
