Is it required to be a member of the Catholic Church as defined by the Vatican (near Rome, Italy), Planet Earth, Solar System, Milky Way, Universe, Creation, in order to be recognized for salvation? Your readers are waiting.

Do you realize that, as someone who has (presumably?) been baptized by the Trinitarian formula, YOU are part of the One, Holy, Catholic and Apostolic Church, don’t you?
