"Endure to the end"; Mormon, Calvinist and Catholic; the same poison!

What do the false man made religious movements, Mormomism, Calvinism and Catholicism, have in common?
They all subscribe to “enduring to the end”, often disguised as the “perseverance of the saints” or “the grace of final perseverance”
“That being justified by his grace, we should be made heirs according to the hope of eternal life. [This is] a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.” (Titus 3:7 to 8)
