It never ceases to amaze me the number of people who define the is-ness of the Church by some sort of idealized doctrinal purity. As if the Church is the result of what one thinks about the Bible. Neither you nor I or any other common man living built or can build the Church. When Jesus said, "On this rock I will build my church" (Matt. 16:18), the Greek word for "build" is the same word used in Gen. 2:22 (LXX). For those of you who may not have figured it out yet, the "one new man" (Eph. 2:15) and the "new creature" (2 Cor. 5:17) of which Paul writes is the Church.
When it is written in Genesis that man is made in the image and likeness of God, "man" here doesn't refer simply to a man but to mankind. God is love and God is triune and neither can be true without the other. Now if mankind is made in the image and likeness of God, then mankind is too a common nature shared among numerous persons. The tragedy of the fall begins first with a division between Eve and Adam through her partaking of the fruit without first seeking counsel from Adam. Adam created a division between God and mankind when he ate of the fruit without seeking counsel from the Father. Through His incarnation (and all that that entails) Christ overcame the division between God and mankind; through His Church, the ongoing manifestation of His incarnation to the world, Christ overcomes the divisions between men and thus in the new creation, the Church, the fall is overcome.
The Church is not a body of doctrine derived from Scripture, it is a body being built by Christ from the body of "Adam" (mankind) since the Day of Pentecost. What does this body look like? Consider Hosea who was asked by God to join himself in marriage to a harlot which relationship then became a symbol for the relationship between God and Israel. Do you think Christ did differently? "While we were yet sinners, Christ died for us" and "gave Himself up for her" (Rom. 5:8, Eph. 5:25). Now if Christ was as physically ugly as the prophet indicated (Is. 53:2-12) and marred by our sins, what do you suppose His body (the Church) looks like after two millenia of being marred by our sins? If you are looking for an outwardly righteous appearing church, then you will most likely fall prey to a false church (2 Cor. 11:13-15, Matt. 7: 22, 23). Those are the ones who are like the Pharisee in the parable about the Pharisee and the Publican. If, however, you sincerely feel like the Publican (Luke 18:10-14), then you are probably on the right track wherever you are coming from.
