And I'm denying the egregious error in this sentence...
"There are hundreds of references in the Sacred Scriptures (Old and New Testaments) to these special beings, created by God as cooperators in the work of salvation."
Neither angels, nor Mary, nor priests who are wrongly tagged as "another Christ," are "cooperators in the work of salvation."
Salvation is the work of Jesus Christ on the cross alone, 100%.
