Thank you all for the replies. As I said in my original post, at this point, it is only an interest. I am new in this forum and I am quickly realizing that SSPX is not very welcome here and that some SSPX members have been even banned.
The situation with the SSPX is very complex and is not settled by any means, to say the least. The Vatican and the SSPX have been involved in discussions for years concerning their reconciliation to the Church and still are unable to resolve their differences. Some will say it is the fault of the SSPX and others will say it is the fault of the Church. The only thing that boths sides really agree on is that the situation complex and ugly.
On this forum you will find people who actively dislike the SSPX and others who actively support them. You will find some supporters who have been banned as well as some who don’t support them being banned. It is not a cut and dried sitiuation by any means.
Currently the SSPX is
NOT in full communion with the Church. The celebrate the Extraordinary Form of the Mass exclusively. They
DO have valid Bishops and valid Priests, but neither group has any authority to perform any Liturgical functions. For instance, they cannot legally celebrate a Mass. ** BUT** if they do celebrate one, the Eucharist that they confect does contain the body, soul, blood and divinity of Jesus Christ in its entirity. The Church has not said that the laity
cannott attend one of their Masses but does not advocate it in any way, shape or form. In fact trhe Church has stated that it can, under certain circumstances be permissable to attend one.
The FSSP was formed by Priests who left the SSPX in order to come into full communion with Rome. They also celebrate the Extraordinary Form of the Mass and are in full communion with the Church. they currently run many traditional Parishes worldwide.
The history and situation of the SSPX is as I said earlier, very complex. Books have been written about it and it is sure to cause a stir when mentioned on these forums.
My advice, until the situation is settled, if you want to go to an Extraordinary Form Mass and the FSSP is available, go there. I would stay away from the SSPX until the matter is resolved unless there was a real emergency.
