Somebody I know who is interested in becoming Catholic was baptized as a teenager, in water, in the name of the Father, Son, and Holy Spirit, and by a Baptist minister who intended to baptize. However, at the time, she believed in some form of Pentecostalism that denied the Holy Trinity. While she was baptized in the name of the Trinity, she did not believe it internally, and I was wondering if this might make her baptism invalid? My first thought is no, because my baptism was valid even though I believed incorrectly about baptism when I myself was baptized (was Baptist). However I wanted to check and see if anyone had any input.
This question comes up because I wanted to give her holy water and the topic came up when I mentioned how holy water is a recollection of one’s baptism. I mentioned how people who have not been baptized don’t really use holy water because of this, and she responded with uncertainty about the validity of her own baptism. So now I’m unsure whether to give her holy water yet.
I know that this is a topic she should speak to her priest about, however I just wanted to ask here for the sake of the holy water thing. She’s leaving tomorrow and I want to give her holy water before then if I should.
Thanks in advance.
