Well, I’m just going to cut through the bush and skip right to the point.
In all likelihood given the description you are talking about Fr. Gruner and his pet project. I have it on good word from a canonist that he is not in good standing with the Church, not does he possess faculties to celebrate Mass or hear confessions where he is located. If you really are itching to double check, contact the
Diocese of St. Catharines (in Ontario), where Fr. Gruner is
not incardinated (if he is in fact incardinated anywhere at all, because that has never been conclusively proven) and has been been running an unapproved ministry for many years. You will notice very quickly that he is not listed as a priest in that diocese, nor is his ministry listed.
EWTN in 2004 listed him as having been suspended.
The short history (as I remember it) was that he was studying for a diocese (in Canada?), and his bishop refused to ordain him (can’t remember why). He eventually was ordained by a bishop in Italy. Fr. Gruner then left that diocese without approval and came back to Canada (without approval). He has been summoned to go back a few times I believe, which he has ignored.
All in all, he’s a priest that should be avoided in all cases except if you are dying and he is the only priest there and you need confession. His propaganda (“newsletter”) should similarly be avoided.
