The truth is not measured by its popularity or its appeal, but by its provenance. One man came to reveal truth, not to say, ‘this is truth,’ but to say, ‘I AM truth.’
Jesus Christ, the only begotten Son of God, is the fullness of truth, the ultimate reality, and the origin of life.
God the Father, the Scriptures, the Prophets and the miracles performed by Jesus, all point to the fact that Jesus is the Way, the Truth and the Life.
The Roman Catholic Church also has provenance, it is the only Church founded by Jesus Christ to deliver that truth, both in Word and Body. The only Church founded by Christ, delivered to the Apostles and handed down to all generations through apostolic succession.
