Ilíon commented:
Is salvation a consequence of membership in, or affiliation with, “the church” (whatever one means by that term), or is membership in the Body of Christ a consequence of salvation?
By “the church”, most people, most of the time, mean some human organization — a bureaucracy with which one may or may not be affiliated. Sometimes, by “the church”, people mean “the Body of Christ”.
Indeed. But it ill behooves us to do theology on the basis of the vernacular use of technical philosophical terms. Properly speaking, the Church is the Body of Christ, and not vice versa. I.e., the Church takes its being from the saving act of the Son in his Incarnation, and not vice versa.
Salvation *is* membership in the Body. To be saved is to put on the mind of Christ, and to be informed by him. The Church on Earth is a sacrament – an outward, material sign of that inward and spiritual Grace. Wherever that Grace is effectual, there is the Body of Christ.
