An unholy church is an oxymoron. God has called us to holiness. He has called us first to a perfect holiness, that which is imputed to us for the sake of Jesus His Son. In this sense, our baptism cannot be improved, and we stand before God as His redeemed people, and we shall sing His praises forever and ever.
But God never justifies without also doing a profound work of sanctification. And if the holiness of sanctification is not there, then we have grounds for questioning if the imputed holiness of justification is. This does not make our justification dependent upon our sanctification. But it does make our knowledge of justification dependent upon the work of sanctification – the kind of holiness your neighbor can see, the kind of holiness your wife can see, and your children.
And so I say again that an unholy church is a flat contradiction, and those who seek to embrace such contradictions shall soon find their lampstand removed. God has begun the work of cleansing His church in this nation. Because of our hardheartedness, the process looks to be thoroughly unpleasant. Turn to Him now, and seek His face. Offer up your heart, your marriage, your household to Him, do it now, and ask Him to uproot every unholy thing.
