My friend just joined a non-denom Evangelical Church. He told me he was baptised a few weeks ago (he’s 38 yrs old). He was baptised as an infant as well. I asked him why he was baptised again and he said that this time it was his conscious decision to get baptised. I don’t understand that logic. As Catholics we acknowledge one baptism. How do I explain our differences to him regarding baptism? If my friend converted to Catholicism would he baptised again?
