However, Vatican II also taught that, within every human heart, God places the law of conscience. Everybody has a deep sense of right and wrong which ultimately comes from God, and which will lead people to God if they attempt to follow their conscience faithfully. Because Jesus is God, those who move in the direction of God (even non-Christians) are ultimately moving in the direction of Jesus. And if they are moving in the direction of Jesus and His truth, ultimately they are expressing a desire for the salvation that God gives. The Church teaches that, while it is certainly easier to receive salvation as a Christian, it is not impossible to receive salvation in other religions.
Can you or anyone give me a Vatican II source for that teaching?
