Granted, the unrepentant are not allowed church membership, nor participation in communion. However, they are to be welcomed to hear and observe the function of the people of God as they worship and administer the sacraments. Only if the unrepentant become seditious or seek to destroy the church, would they be barred from services. This view sees the church as representative of Christ's dominion. She actively proclaims the Crown and Covenant of Christ in every sphere of life.
Separatists are very uncomfortable with what they deem mixture.
The church for them is exclusive to those already redeemed. This is certainly true regarding formal membership, but the separatist extends this exclusivity to church attendance as well. Hence, the separatist is frightened by sinners defiling the sanctuary. In this sense, separatists are less like the Church and more like John Wesley s Holy Club. This model regards the church as a monastery endeavoring to evade evil rather than confronting and vanquishing it.
