Like St. Athanasius?
St. Athanasius
Fighter of heresy, falsely accused, ridiculed, condemned, removed from office by heretics and church hierarchy, banished for over ten years, returned, expelled for a second time, continued to fight for the Faith, the entire world against him, "no friends but God and Death...," died, and ultimately declared a Saint.
Huh? St. Athanasius was no schismatic.
Please don't besmirch the memory of this great Doctor of the Church.
