Those are just among the 7 Deadly Sins; what about the 10 Commandments? Any members who swear and take the name of God in vain? Disrespect their parents? Adultry? Covet? Take what does not belong to them? Perhaps place more value on money, land, family or wealth than they should?
Perhaps what is really needed is a Church (with a capital C) that behaves more like a Church: calling sin "sin" and calling on sinners to truly repent and change their ways.
Just a thought....
The difference is, even if you commit one of the 7 deadly sins, you admit it's wrong. Does the gay guy think his lifestyle is wrong?
Becoming a church member means that you accept the tenants of faith that the church proclaims. A church member votes on leadership, bugeting, etc. People who don't agree to the tenants of faith (in this case, the Bible states that homosexuality is a sin and must be repented of) are not eligible for church membership. They may attend church and worship but they cannot vote or be elected to leadership positions.
That being said, everyone sins. The difference is, are you repentent and asking God to change you from within? Acknowledging your sin before God and man is a requirement. Once that is done, forgiveness is available to everyone, no matter the sin they repent of.
The church body is to be protected. God is Holy whether people like it or not. If God wasn't holy, we wouldn't have needed Jesus in the first place.
