Mt 18:17 And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican. These are the words of Christ speaking about church disipline. The greek word ekklesia is used for church. This word means called out assembly. I don't think the church could have come into existance until after the veil was rent and there was the death of the testator. Could the church have existed while Christ walked the earth?
