2589. THE STATE AND CONDITION IN THE NEXT LIFE OF NATIONS AND PEOPLES BORN OUTSIDE THE CHURCH
It is commonly supposed that those born outside the Church, who are called heathens and gentiles, cannot be saved for the reason that they do not possess the Word and so do not know the Lord, without whom there is no salvation. But that gentiles too are saved may be known from the single consideration that the Lord's mercy is universal - that is, it reaches out to every individual human being. For gentiles are born human beings the same as those within the Church, who are a relative minority; and they are not to blame because they do not know the Lord. Consequently the nature of their state and condition in the next life has in the Lord's Divine mercy been shown to me.
Isaiah 45:14
14
Thus says Yahweh: "The labor of Egypt, and the merchandise of Ethiopia, and the Sabeans, men of stature, shall come over to you, and they shall be yours. They will go after you. They shall come over in chains; and they will bow down to you. They will make supplication to you: 'Surely God is in you; and there is none else. There is no other God.
