Dear James:

Thanks for the notice.  Schism is a specific canonical state of a person or group. Canon Law gives a short definition:

Can. 751 Heresy is the obstinate denial or obstinate doubt after the reception of baptism of some truth which is to be believed by divine and Catholic faith; apostasy is the total repudiation of the Christian faith; schism is the refusal of submission to the Supreme Pontiff or of communion with the members of the Church subject to him.

I took a quick look at the site. I did not find anything that was schismatic. Perhaps I missed it. What I did find was disparagement of Vatican II Council and other Ultra-Traditionalist nonsense. They apparently also a part of the "The Third Secret of Fatima was never revealed" group of arrogant loony-tunes, along with the likes Fr. Gruner of the Fatima Network and Fatima Crusader, which all Catholics should avoid.

While technical schism may or may not be the case, these people are not to be recommended.

This a warning is warranted. Beware of this site the ageofmary site. Find resources elsewhere. Do not go to them even for the Little Office as that would be supporting their website.

God Bless,
Bro. Ignatius Mary
