No one can be saved merely by living according to the beatitudes. This is what the Church teaches: "For by grace you are saved through faith, and that not of yourselves, for it is the gift of God". Peter speaking here. Acts 4:11-12 This Jesus is the stone that was rejected by you, the builders, which has become the cornerstone. And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.”
