The Purity of the Church, Not the Size

I do not understand that mentality in the Christian Church today which says that we must all come together and sink our differences; and that what we believe does not matter. It is a denial of the Book of the Acts of the Apostles, and of the story of the twelve ignorant, untutored and unlettered men who knew whom and what they believed, and who had the power of the Spirit upon them, and who 'turned the world upside-down'.

This is surely one of the central messages of the Bible. The great concern of the New Testament Epistles is not about the size of the Church, it is about the purity of the Church. The Apostles never said to the first Christians: " You are antagonizing people by emphasizing doctrine. Say more about the love of God and less about the wrath of God. They do not even like the Cross, and they cannot abide the story of the resurrection! Drop that talk about the wrath of God and Christ's ethical teaching!" Not so do the Apostles speak!
