No one is pretending to be God except for men who call themselves "another Christ" or people who mistakenly think there is a "co-redeemer."
Further, do you not know "who receives salvation through Jesus?" Is that a mystery to you?
"But ye believe not, because ye are not of my sheep, as I said unto you. My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand." -- John 10:26-29
"Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened." -- Matthew 7:7-8"Be not afraid; only believe." -- Mark 5:36
"Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only the one who does the will of my Father in heaven.
What is "the will of the Father?"
"Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent." -- John 6:29
That term alter Christus is being distorted beyond all recognition. The Catholic Church does not teach that each priest is some fresh new Messiah.
...or people who mistakenly think there is a "co-redeemer."
That term too is being distorted, and is not even a teaching of the Catholic Church.
The same falsehoods about Catholicism are repeated here over and over, as a fetish, regardless how many times they are corrected. What can the motive be?
