My reason for asking was that I was hoping it would never come up again…that I could enter religious life without having to “re-hash” it, so to speak, in order to get permission to enter. If I’m understanding correctly, it is only an impediment for those becoming priests, but not for nuns?
The current canon law regarding admission to a novitiate is as follows;
*Can. 642 With vigilant care, superiors are only to admit those who, besides the required age, have the health, suitable character, and sufficient qualities of maturity to embrace the proper life of the institute. This health, character, and maturity are to be verified even by using experts, if necessary, without prejudice to the prescript of ⇒ can. 220.
Can. 643 §1. The following are admitted to the novitiate invalidly:
1/ one who has not yet completed seventeen years of age;
2/ a spouse, while the marriage continues to exist;
3/ one who is currently bound by a sacred bond to some institute of consecrated life or is incorporated in some society of apostolic life, without prejudice to the prescript of ⇒ can. 684;
4/ one who enters the institute induced by force, grave fear, or malice, or the one whom a superior, induced in the same way, has received;
5/ one who has concealed his or her incorporation in some institute of consecrated life or in some society of apostolic life.
§2. Proper law can establish other impediments even for validity of admission or can attach conditions.
Can. 644 Superiors are not to admit to the novitiate secular clerics without consulting their proper ordinary nor those who, burdened by debts, cannot repay them.
Can. 645 §1. Before candidates are admitted to the novitiate, they must show proof of baptism, confirmation, and free status.
§2. If it concerns the admission of clerics or those who had been admitted in another institute of consecrated life, in a society of apostolic life, or in a seminary, there is additionally required the testimony of, respectively, the local ordinary, the major superior of the institute or society, or the rector of the seminary.
§3. Proper law can require other proof about the requisite suitability of candidates and freedom from impediments.
§4. Superiors can also seek other information, even under secrecy, if it seems necessary to them.*
Past mistakes, and expired penalties or privations (including excommunication) are not a bar to application unless the proper law of an institute (the rules specific to that institute) say otherwise.
It is perhaps worth saying that it is rarely a good idea to hide things during an admission process, however. Total honesty is difficult, but it really is preferable, so that there are no misunderstandings, and no fear of later discovery. Try to trust that God will lead you to people of compassion with whom you can share your past, and with whom you can share your future too.
Best wishes and prayers that you will be a great gift to the church when God shows you the life He has prepared for you.
