Catholicism.... The acolytes of Fatima would almost certainly regard Orthodox Christianity as heretical. First for being schismatic by claiming to be the ‘true church’ and rebellious for denying the authority of the ‘seat of Peter.’
I’m good with this. Christ was schismatic by returning to Scripture instead of any man-made religion. There is no position in Scripture to appeal, to worship or place any hope or trust in besides Jesus Christ.
Matthew 28:18 - KJV
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
“All” means all.
