Only Protestants believe in denominations. The Lord founded His Church, the One Holy Catholic and Apostolic Church, on Saint Peter's confession. His Church continues to this day. You have CHOSEN to separate yourself from His Church.
His elect will be saved.
Thus spaketh Calvin.
and Paul, and Christ...
The RCC was not founded by the Lord - that’s a fairy tale from the RCC founders. Peter was not a pope - that office was invented by the politicians who were in cahoots with the Roman bishops of the 4th century.
Regarding the salvation of the elect, I refer you to the words of Christ, recorded in Matthew 24:29 -31 “Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: “And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.”
Reconcile with Christ, not Calvin. Read the Word of God, not the words of man.
