My mother hasn’t set foot in her Episcopal church for at least ten years, but they send her her pledge every year.
The crazy thing is she pays it. Very disturbing.
At no time during that ensuing time has anyone contacted her to ask her whether she has a problem with the church, or even more so, does she need help personally? (Yes to first, no to second). Basically, so long as they get the money, they don’t care if anyone is coming.
Does your mother have a church she does attend? That should be the most important issue.
The failure of anyone from the parish to contact her is very telling. The Episcopal Church is dying, and negligence like that is a major cause. Gene Robinson is just a symptom.
She might try withholding her pledge, or even just delaying sending it in. Someone from the vestry would probably contact her pronto.
