We must now consider venial sin in itself, and under this head there are six points of inquiry:

A[1] Whether venial sin causes a stain in the soul?

A[2] Of the different kinds of venial sin, as denoted by "wood," "hay," "stubble" (1 Cor. 3:12);

A[3] Whether man could sin venially in the state of innocence?

A[4] Whether a good or a wicked angel can sin venially?

A[5] Whether the movements of unbelievers are venial sins?

A[6] Whether venial sin can be in a man with original sin alone?
