One Authority

"Amen, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven." (Matthew 18: 18)

It is clear from the above passage that Christ left for the Church a clear authority to act. This conclusively shows His intention and desire that there be only one Church. In a situation of multiplicity of churches, there would be multiple and contradictory authorities as we see with the interpretation of the same scriptures. In a different scripture Jesus says:

"Whoever listens to you listens to me. whoever rejects you rejects me. and whoever rejects me rejects the one who sent me." (Luke 10: 16)
