You need a little history lesson, my friend. The Church existed long before the first letter of the first gospel or first epistle was written. Just where was its moral authority coming from during the period before and during the writing of the gospels, the last of which was not even completed until after 90 A.D. And who do you think determined that the Gospel of John was inspired and that the apochryphal Gospel of Thomas, for example, was not. I will tell you where the Church gets its moral authority: From the lips of Jesus Christ himself: Take a good look at Matthew 16:18-19. "You are Peter and upon this Rock I will build my Church....What you declare bound on earth shall be bound in heaven, what you declare loosed on earth shall beloosed in heaven." Your personal revelation, as you call it, is just that. It has absolutely no assurance of moral rectitude in the sight of God. The Church declared which books of the Bible were divinely inspired and you, in the face of Christ's clear instruction, deny it the right to interpret the scripture and contend it lacks moral authority, because the authority reposes, by Christ's command, in His vicar on earth. So be it.
The point that you and many others fail to understand is that the Church, as an institution, is both divine and human. Because it is human, its followers will sin. This does not lessen its moral authority, because this authority comes from Christ and is not dependent on whether you or the Gallup Poll or any other human being judges it to be hypocritical. If you don't agree with its teachings, you are free to reject it. But don't use the argument that the Church is composed of sinners as an excuse for doing so.
As I said, the Church is both Divine(Jesus)and human(His followers). It is thus a blend of light and darkness. It radiates enough light for those who want to see and enough darkness for those who don't.
Well said. God bless.
