Modern-day decree of excommunication
Archbishop Burke’s Decree of Excommunication against the schismatics can be found here. Go read it.
A discussion of the canonical implications of the decree can be found here. Read this too.
Note this paragraph:
Wherefore, the entirety of the Catholic faithful of the Archdiocese of Saint Louis are warned by the present Declaration that any of the Sacraments attempted to be celebrated by Patricia Fresen, Rose Hudson and Elsie McGrath are utterly null and void; and that any assistance or attendance at, and direct or indirect participation in their supposed sacramental rites or rites of prayer are strictly forbidden.
What penalties would a Catholic from Saint Louis who did participate in those rites incur? And would a Catholic from outside Archbishop Burke’s jurisdiction also incur penalties?
