Mass Baptism or mass baptisms? I suppose if you have holy water and say "I" instead of "we" and sprinkle the whole group of unbaptized desiring to be baptized you are legal church wise. Wives and husbands could be baptized with their partners.
For me it was that my parents required me to attend a religious elementary school (my school was Lutheran) and I didn't know any other way. I'm sure that is true for many other posters.
I believe the same but in the end they have put a great deal of stress on people who now believe they are going to hell or that their relatives/mates went to hell.
