When I entered the Catholic Church, I was not able to get certificates of my Baptism and Confirmation. The church where I was baptized/confirmed somehow couldn’t find the information. However, I was old enough to remember the event and had witnesses. The Catholic priest asked me to get signatures of two witnesses, which I did. Then, I was able to enter the Catholic Church and I received a certificate saying that I received all my Sacraments of initiation. My baptism was valid because it was done in an Orthodox church.
What I was wondering is… if I ever enter a religious order, would it be enough to present to them the certificate I got when I became Catholic, or do I need particular dates of my Baptism and Confirmation too? I don’t know if that would ever be found. I can try again, but what if it doesn’t work?
In Canon Law it says “Can 645 §1 Before candidates are admitted to the novitiate, they must show proof of baptism, confirmation, and free status”
