"Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep. All that ever came before me are thieves and robbers: but the sheep did not hear them. I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly. I am the good shepherd: the good shepherd giveth his life for the sheep. But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep. The hireling fleeth, because he is an hireling, and careth not for the sheep. I am the good shepherd, and know my sheep, and am known of mine. As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd."
Please forgive any errors in my explanation, I have only had my nose in this book called the Bible most of my life because I have not had anything else but very few and widely scattered mentors.
Jesus said he had 'other sheep which are not of this fold' and that He would bring them and there would be ONE fold, ONE shepherd. Years of Bible study have taught me that Jesus was talking to Jews (His chosen flock) and the other sheep were Gentiles (Greeks).
So where is the one fold? You would probably say the canonical Eastern Orthodox church. Okay. So if Jesus says those other sheep would hear His voice and He would bring them why are they kept out? The hireling is at the door? Wounded, travel weary sheep are coming and told they are 'not orthodox' and they stay for awhile seeing Jesus and not being allowed to approach and after they are thoroughly broken they leave disillusioned. I am not orthodox, but I am one of Christ's sheep. Is Christ simply in other Christians who I see bear the Fruits of the Spirit? I am very close to hanging up my searchings for His church in this elusive thing called orthodoxy.
