There’s no question that those who think that Catholic teaching goes beyond the catechism and the bible are wrong
The church doesn’t have any teaching that is unspoken unwritten and secret
Drop it
You are ignorant of the facts
And you are lying about the Church
The ignorant one here is you. The Catechism devotes a whole section to the "...no salvation outside the Church..." teaching and what it means.
From the Catechism:
845 To reunite all his children, scattered and led astray by sin, the Father willed to call the whole of humanity together into his Son's Church. The Church is the place where humanity must rediscover its unity and salvation. The Church is "the world reconciled." She is that bark which "in the full sail of the Lord's cross, by the breath of the Holy Spirit, navigates safely in this world." According to another image dear to the Church Fathers, she is prefigured by Noah's ark, which alone saves from the flood.334
"Outside the Church there is no salvation"
846 How are we to understand this affirmation, often repeated by the Church Fathers?335 Re-formulated positively, it means that all salvation comes from Christ the Head through the Church which is his Body:
Basing itself on Scripture and Tradition, the Council teaches that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and Baptism, and thereby affirmed at the same time the necessity of the Church which men enter through Baptism as through a door. Hence they could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it or to remain in it.336
"And you are lying about the Church...
And the only liar here is you.
That's two strikes. Care to try for three??
