Well, Matt, let’s look at the possibilities.
Suppose a priest at a Church is approached, “Father baptize my child.”
“Well, friend, I see you at church regularly. I don’t know though about your Catholic faith. You see, you don’t use envelopes, so I don’t know if you contribute to the Church --which is one of the precepts–at all. If you don’t contribute to the church, and if I have only seen you there maybe the last year or two I’ve been serving, how can I be sure that you are going to raise this child Catholic when I don’t have any real record that you’re doing anything Catholic? I mean, this is a big church, and despite your ‘faithful attendance’ I might not have noticed your shining aura of sanctity or know you personally. That’s why I started the envelope policy. . .that way I know if you’re going to Mass and supporting the Church and even though it’s not 100% effective (nothing is), at least there’s a pretty good tangible proof that you are following the Church rules and that is a good indication you would bring up your child Catholic.”
Perhaps, Matt, this particular priest or this particular parish had had some very painful repercussions of people just saying, "sure, bring in the kid’, 'child is baptized and family NEVER DARKENS THE DOOR OF A CHURCH AGAIN and then years later child comes for confirmation or marriage and can’t understand why he ‘has to’ receive sacraments which he was never brought for, or why he can’t get married out in the woods, etc. etc.
Lucky St. Peter and St. Paul. All THEY had to worry about was death or torture.

Oh wait, don’t I remember from Acts that with the Greek members complaining their widows weren’t getting served that the apostles ‘laid on hands’ and established men to take care of the bureaucratic details? I’ll just BET that Philip and Stephen, for example, didn’t handle things EXACTLY THE SAME WAY (because Philip’s church, for example, was full of gladiators and Stephen’s full of widows, and gladiators had more cash and more problems with drinking and sex and Stephen’s had more troubles with family issues) so that when Roscius the gladiator came in for baptism it was pretty straightforward, but when Claudia the widow came in at 9 p.m. with her grandchildren but NOT the children’s parents it might have been a little more, um, involved.
