Fr. Dimitry Dudko, in the little newspaper he puts out, said there came it him someone who claimed to be Christian. As he began to talk to him, he began to feel that this person wasn’t Orthodox, and he said, “What confession are you?” “Oh, that’s not important. We’re all Christians. The only important thing is that we be Christians.” He said, “Well, no, no, we have to be more precise than that. For example, if you’re a Baptist and I’m an Orthodox, I believe that we have the Lord’s Body and Blood, and you don’t.” We must be precise because there are many differences. It’s good to have the attitude: I have respect for you, and I won’t interfere with your faith, but nonetheless there’s a true way of believing and there are ways which go away from the truth. I must be according to the truth.
In the same way we can see that many people who ae not Orthodox have many good things about them, and then they go off in some respect. In the end it’s up to God to judge, not to us. But we can see what will happen if all these little ways people go off now are projected into the last times, if people still believe that way when the last times come. These mistakes cause people, when they see Antichrist, to think that he is Christ. There are very many sects now which believe that Christ is coming to rule for a thousand years form the Temple in Jerusalem. Therefore, when the Jews start building the Temple, these sects will only rejoice because, to them, this is the sign of Christ’s coming. On the contrary, we know that this isn’t he sign of the Antichrist coming, because Christ will no more come to the Temple. The Temple has been destroyed. Christ comes only at the end of the world to begin the eternal kingdom of heaven. The only one who will come to the Temple is Antichrist.
