This is not well supported by Scripture, Ravenwolf. The Church has always been, and still is still made up of sinners. Jesus specifically says, in Matthew 13:24-30, that the Kingdom has wheat and weeds growing in the same field, and will have until the end of time. Every society, including the Church, has to have laws to, as you say, "hold down corruption" --- that's why Jesus gave St. Peter the Power of the Keys of the Kingdom, which is, the power to make laws, to govern.
The Kingdom will never be entirely pure and without corruption until we are all safe in Heaven with our good Lord. Praise to Him forever!

Also i do not see the kingdom of God as being the same as the kingdom of heaven.
The kingdom of God is within you now, but at the great harvest you will be gathered up to heaven.
I say you, but i hope me too.
