Millions of Christians have ALL had a connection to the Catholic church...for example, if they were properly baptized, they were baptized Catholic...you cannot be baptized into a false denomination.
You can’t stuff the millions of baptized Biblical Christians into your Catholic denomination, the Holy Spirit will not allow it.
God sees thing differntly than Catholics seem to.
You wish to have baptism represent being baptized into your denomination, fine.
Biblical Christians are not baptized into a denomionation, but into a personal born again relationship with Jesus.
That is a proper baptism and has nothing to do with your denomination.
The only people that have a connection to the Catholic church are the ones that choose to. Or are born into it and are therefore usually stuck in it.
Very few Biblical Christians choose that as the joy and peace of having a born again personal relationship with Jesus has the closeness desired.
