No Catholic denomination would have someone already baptized in a Southern Baptist church "baptized again". Southern Baptists believe in the trinity and do a water baptism in the name of the father, son, and holy spirit, thus it is a valid Christian baptism (unlike Mormon "baptisms" and other churches that do not accept basic Christian doctirnes) The Catholic Church believes only ONE valid baptism may be performed on a person. A second baptism would be meaningless since God accepted the first one.
However, if Jindal was baptized in a Baptist church and later converted to Catholic, he would be eligible to receive the sacraments of Confirmation and Holy Communion.
If Jindal disclosed that he had already been baptized.
I’m well aware that Catholics only allow one baptism, but this issue with Jindal is unclear.
It is also a detail that is difficult to research, because it is the kind of religious detail that doesn’t get covered, asked about, or investigated, by the media.
