CCC 1271 Baptism constitutes the foundation of communion among all Christians, including those who are not yet in full communion with the Catholic Church: “For men who believe in Christ and have been properly baptized are put in some, though imperfect, communion with the Catholic Church. Justified by faith in Baptism, [they] are incorporated into Christ; they therefore have a right to be called Christians, and with good reason are accepted as brothers by the children of the Catholic Church.” (2nd Vatican Council, Unitatis redintegratio 3) “Baptism therefore constitutes the sacramental bond of unity existing among all who through it are reborn.” (ibid., 22 § 2.)
This got me thinking, how many “Christians” are there out there that aren’t actually Christian?
The New Church?
Am I right to believe that these groups, that do not accept a Trinitarian baptism, are not Christian at all?
