Do Sins Interrupt our Communion with Christ?

Do sins interrupt our communion with Christ?

Theodor Jellinghaus, the Perfectionist:

The Christian should and can become pure and remain pure from all sins and all impurity of a kind to interrupt his inner communion with God and his peace with Jesus.

B.B. Warfield:

Of course these is no sin of conduct and no sinfulness of disposition, of whatever sort, kind or degree, the proper effect of which is not to interrupt our communion with God and our peace with Jesus. If it does not actually interrupt our communion with God and our peace with Jesus, that can only be because our communion with God and our peace with Jesus have their ground not in our own holiness, but in Christ Himself–rest, in accordance with I John ii. on what Jesus has done for us and is doing in us, and not on any works or attainments of our own. The effect of Jellinghaus’ statement is to declare that there are some sins God will tolerate in His children and some which He will not. This seems to reintroduce the exploded distinction between mortal and venial sins, and appears to license Christians to commit a certain class of sins.

Armesünderchristentum: A Doctrine of Penitent Sinners

The reformation doctrine of “miserable sinners” is a doctrine of penitent sinners. It has no application to the indifferent or the secure. It offers itself only to those who, broken-hearted in repentance, look to Jesus alone as their compassionate Savior, and tells them that for them too Jesus alone is enough. It does not tell them that they are not sinners; that would not be true, and they know it is not true; no one know himself a sinner like a penitent sinner. It tells them that they are saved sinners–and that is the most glorious thing it could tell them.
