Catholics do not baptize Christians....they only baptize NON-Christians who have NOT been baptized.
Yes, I know, for instance the Catholics baptize Mormons when they become Christians, all Christian churches do.
My late mother in law, who I knew believed in Jesus and His teachings, went into a coma a few weeks before she died. My husband and I were discussing how her funeral arrangements would be handled. I am born and raised Catholic and my husband converted after we were married. My mother in law always spoke of how she admired Catholics and the Catholic religion. So I suggested that we have her baptized so she could have a Catholic burial. We called our priest to ask his advice on this, and he asked if she had ever been baptized before as a Christian, and we had no idea if this was the case. So he came to the hospital and conducted a “conditional Baptism” and gave her the last rites. Within a day, she regained consciousness and was delighted when we told her that we had her baptized while she was in a coma. She confirmed that she had never been baptized and so the priest removed the “conditional” and she was formally baptized into the Catholic Church. She eventually died within the next two weeks, and she had a full Catholic burial. The priest, at her Mass, said that upon her baptism all her sins were now forgiven and she would be able to go straight to heaven.
What’s special about that is that when my husband was conceived, she and my father in law were having many marriage difficulties and she did not want another baby. My husband would be her 4th. She went to a nurse and the nurse gave her some sort of pill that would “bring her period down”, or abort my husband. Well the pill didn’t work and my husband was born. The same baby she tried to get rid of was responsible for her baptism at the end of her life and helped save her soul.
