Say, I think a big factor lost in many of these threads – at least in this sub-forum – is that of the role of the Parish and Diocesan workers themselves in answering questions relating to ex-members of SSPX Society Chapels.
Hey, it works like this:
Today *Willie Roe *is a hard-charging university student, majoring in Rocket Science.
He was raised as little or nothing by parents who themselves had no formal religion.
In his early teens, Willie Roe stumbled into a SSPX Society Chapel, and over the course of x amount of time was baptized and made his First Communion, eventually being confirmed by Society Bishop Y.
Now, Willie Roe won’t go near the place.
Ever so often he goes to Mass at a regular diocesan church, but wants to know: “What do I have to do?”
HINT: In my diocese at least, practically nothing at all. I know 'cause as an auxiliary member of the local diocese palace guard myself, I knew which DRE to quietly ask on Willie’s behalf, and got both of us a straight answer.
MORAL? “If in doubt, ask your DRE!”
She’ll know all about SSPX marriages, baptisms, first holy communions, etc.
And, no! “She won’t bite you!”
