I grew up in a Protestant Church of Christ since I was a baby. I was baptised when I was eleven and baptised again when I was seventeen.
I have a few questions in regard to this:
It’s my understanding that, in the Catholic Church, baptism is a sacrament. By nature of a sacrament (in difference from a sacramental) the spiritual state of the recipient of the sacramental does not matter during the sacrament. i.e. a groom who is in the state of mortal sin when he gets married is still validly married.
Does the same apply to baptism? I ask because I understand that the Catholic Church accepts baptisms from some Protestant churches as valid sacraments. I don’t necessarily have to be baptised again to become Catholic.
Where I’m struggling, is with my second baptism at age 17. The day of, I was reading my bible and I came across some verses that I really didn’t like. Romans 9 for those of you familiar with the controversy surrounding that chapter. I had never seen the verses before and I was struggling with intense doubt at the time. I got baptised with shaky knees and I didn’t even know if I wanted to do it. I poured out my soul to God in tears when I got home.
Now, I understand that the Catholic Church teaches one baptism. Once baptised, it cannot be undone or redone. Does this, coupled with the fact that the spiritual state of a person does not matter during a sacrament mean that my baptism was valid? If I wanted to get baptised Catholic when I decided to convert, could I do that? Would it be a lack of faith? Or a sin?
Thank you for your time, patience and consideration
