An assumption read back into Christ's words, which He does not say.

As is the Protestant understanding of "being saved."

The difference is that being saved from the wrath of God, having salvation now and in the future, etc. are all Biblical revelations from the Apostles. The rosary is made up from whole cloth.

An assumption read back into Christ's words, which He does not say.

As is the Protestant understanding of "being saved." Well let's go with what The Word Jesus says then:

King James Bible
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.

King James Bible-Acts 16:31
And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.

9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.-Romans 10:9.10

It's best to be careful about declaring something completely counter to God's word.
