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

A1 Whether venial sin causes a stain in the soul?

A2 Of the different kinds of venial sin, as denoted by "wood," "hay," "stubble" (1 Cor. 3:12);

A3 Whether man could sin venially in the state of innocence?

A4 Whether a good or a wicked angel can sin venially?

A5 Whether the movements of unbelievers are venial sins?

A6 Whether venial sin can be in a man with original sin alone?
