Chapter 12 — Part I: The Creed — Article X: The Forgiveness of Sins
Section 20. Abuse To Be Guarded Against — But here the faithful are to be admonished to guard against the danger of becoming more prone to sin, or slow to repentance, from a presumption that they can have recourse to this power of forgiving sins which is so complete and, as we saw, unrestricted as to time. For, as such a propensity to sin would manifestly convict them of acting injuriously and contumaciously to this divine power, and would therefore render them unworthy of the divine mercy; so this slowness to repentance gives great reason to fear that, overtaken by death, they may in vain confess their belief in the remission of sins, which by their tardiness and procrastination they deservedly forfeited.
