Key Points: The UNIQUE AUTHORITY of the Catholic Church: Jesus started ONE Church ( Mt16:16-19 ), prayed for UNITY in that Church ( Jn .17 ), intended for that Church to remain until the end of human history ( Mt 28:20 ), gave that Church the Holy Spirit to guide it into all truth ( Jn 16:13 ), and gave that Church the Unique Authority it would need ( Mt16:16-19 ). That Church even preceded the bible. That Church (that Jesus started) is “The Pillar and Foundation of truth.” ( 1Tim 3:15 ) The Authority issue is essential in solving doctrinal differences between Christians.
