I see what Schaeffer is saying--religion and such terms can define us too much to the point we become like Pharisees, saying, "I am Orthodox." "I am Christian" without professing the true faith or being of Christ. But the Councils make clear there are certain things which are true doctrine and you confess those things as in the Creed and in the Councils. You detest what the Fathers have condemned in the Holy Councils as heretical and anathema, and you believe what they profess. Orthodoxy is not just about a pretty show where you can take your kids and feel good and welcomed, unlike those awful self-righteous Evangelical churches. I would ask if he is ready to sternly condemn the errors of various heresies, not because they displease him romanticism, but because they are false and ugly, outright blasphemy. Does he believe in "one God, the Father Almighty, maker of heaven and earth and in Jesus Christ His Son, begotten of the Father before all the ages, God of God, True God of True God...not made in time nor of the father or less, but begotten of Him, one in the same divine essence with him." You know all that important stuff. Or is that just stuff the stuffy types talk about to turn atheists off?
