You are correct.
The belief that one's religion is the "one true faith" is called "triumphalism," and it is now forbidden in the Roman Catholic Church as is proselytism, which is evangelizing by employing techniques that compares "our true religion" with "your false religion."
The Roman Catholic Church, since Vatican II and especially since the reigns of St. Pope John Paul the Great and now Pope Francis teaches that G-d is not limited by denominational lines or any particular means in G-d's distribution of "truth," which the RCC refers to as "the economy of salvation."
This change in doctrine includes the view that people can fulfill G-d's purpose in ways not understood by the Church, and that the Church relies on the fact that the covenant between G-d and the Jews is still intact (which is also why attempts to convert the Jews is a big "no-no" now in Catholic circles).
