What?

Look in the Catechism at the heading between CCC 845 and 846:
“Outside the Church there is no salvation”

[InMemoriam]

Have you read the section Wounds to unity? It begins at CCC 817.

Lumen Gentium: "This is the one Church of Christ which in the Creed is professed as one, holy, catholic and apostolic, (12*) which our Saviour, after His Resurrection, commissioned Peter to shepherd, and him and the other apostles to extend and direct with authority, which He erected for all ages as "the pillar and mainstay of the truth". This Church constituted and organized in the world as a society, subsists in the Catholic Church, which is governed by the successor of Peter and by the Bishops in communion with him, although many elements of sanctification and of truth are found outside of its visible structure. There you go. Pope Paul VI has stated it clearly.

And 847 teaches: "This affirmation is not aimed at those who, through no fault of their own, do not know Christ and his Church: Those who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience - those too may achieve eternal salvation" I'm a convert, what's your excuse?
