This article takes some very strong liberties with Scripture to come to it's conclusions. I am not willing to do that in order to figure out what Scripture says.
There are no liberties with scripture.
The scripture is printed out in full along with each comment.
Anabaptists lose 80% of their kids to "the other team" within five years' of those kids leaving home. Hard-core calvinists and home schooling families keep 90+% of their kids. This may have to do with contrasting visions of salvation: a one-point gnostic experience, vs. an ongoing growth in grace and in the knowledge of the Redeemer.
