You know what is funny. I had a lunch meeting with Patrick Madrid while he was in Greenville, SC. I highly doubt that a homeschooling father with 11 children who preached to a Novus Ordo church (where the pastor is unfriendly to the Traditional Latin Mass) about his love and devotion for the Traditional Latin Mass, and recommended the indult at a different parish, could really be considered a modernist.
But perhaps you personally know more about it than I do...
But then I wouldn't look to anyone other than the Church to determine what is of the Church, and what is not.
