This is wrong, I am not a SSPX attendee, but I feel I should defend them from mischaracterization. They are not Schism, nor do they deny Apostolic Succession. They are fully Catholic, but the Society has no canonical recognition as of yet in Church, as such no Bishop has allowed them to be in their Diocese, and given them necessary faculties to minister. Their Masses are valid, but not licit, I know there has been much arguing over the point of whether or not attending their Mass fulfils one’s Sunday Obligation, but I will repeat what one of the priest at my parish said “…it does.” The Sacraments of Marriage and Penance are, unfortunately, not valid, since they require said faculties from the Bishop in whose Diocese they operate. They do recognize Pope Francis as the legitimate heir to the Chair of St. Peter.
