"For those who have eyes and can read there is the historical record" [excerpt]
LOL, the Holy Writ wasn’t written during the public ministry of Our Lord nor by Him. The same men that wrote the Holy Writ wrote many of the First Century reports of the Universal Church as it grew. The earliest Catechism is http://newadvent.org/fathers/0714.htm — written about 70 years after the Crucifiction and Resurrection of Our Lord.
