Your statement: “That means that everyone who has ever been baptized is saved...”
Jesus said that Baptism is necessary for salvation, not that Baptism assures salvation. One needs to lead a moral life and die without mortal sin. Our individual salvation is determined by Jesus upon our death.
Baptism by God’s grace forgives original sin and actual sin at the time of Baptism. Confession or Reconciliation forgives sins after Baptism.
Christ died for our sins and opened the opportunity for Heaven for those who believe in God and attempt to do God’s will on earth. We gain Heaven by God’s grace, but we can lose it by our actions and sins.
then why didn't HE go around baptizing and telling people that they were saved because they were baptized instead of by faith?
He told people that their faith had saved them.
Ritual cleansing of the body does not cleanse the conscience or the soul.
It doesn't say that without baptism there is no salvation. Without the shedding of blood, there is NO remission of sins. Baptism is NOT the shedding of blood.
None of which can be supported in the least by Scripture.
It's all simply claimed by the Catholic church, which clearly isn't relying on Scripture for those teachings of its.
