parentsfortruth - you can easily find out about your chapel, all the business records should be public records, if they are a non-profit, which I would assume they are.  you could do a search for it online.  from the tax records, you should be able to find the articles of incorporation along with who are the board members.  that would be a start.

Unfortunately, it can take two to three years before those records are generally "available" from open sources.  By then, it will be too late.

From my research, he served 18 years as a parish priest in the archdiocese of Philadelphia. He was also in the military and was quite decorated. He was with the SSPX for 3 years before leaving. He's been at the SS. Peter and Paul Mission since 2010. The SSPX wouldn't have kept him there if he weren't legit, and my suspicion is that he was conditionally reordained. Marie Auxilliadora would know more, I'm sure.

I also wanted to mention that I found out what they signed with the SSPX. They agreed to give the SSPX 5% of the donations from the collection plate.
