Listers, the “9 Ways of Being an Accessory to Another’s Sin” is taken from the 1962 Roman Missal under the heading of “The Most Necessary Prayers.” The list is commonly used as part of the Catholic’s examination of conscience before receiving the Eucharist. The list is simple, but a necessary guidepost for those striving after the Christ-centered life of virtue.

I. By counsel II. By command III. By consent IV. By provocation V. By praise or flattery VI. By concealment VII. By partaking VIII. By silence IX. By defense of the ill done


Further drawing from the 1962 Missal, St. Peter’s List has published a list of morning prayers and a list of night prayers. Those wishing to know more about the Missal and its essential role in the family can turn to The Domestic Church: 7 Steps to a Proper Catholic Home.
