1. About the Idea of the Name ‘Satisfaction’ Taken Strictly

44. On the first point [n.43] I say that ‘satisfaction is an exterior operation, laboring or penal, voluntarily undertaken, for punishing a sin committed by oneself, and this for placating divine offense’; or it is ‘a passion or penalty voluntarily borne in its order to sin or the remission of sin’. This is much stricter and more particular than satisfaction in the first way [nn.11-16], because that one can consist in an interior or exterior penal act of voluntary suffering.
