The Christian doctrine which Protestantism emphasizes is that every human being, irrespective of family, class, or occupation, is unique before God; the complementary and equally Christian doctrine emphasized by Catholicism is that we are all members, one with another, both in the Earthly and the Heavenly City.
Or one might say that, in conjugating the present tense of the verb to be, Catholicism concentrates on the plural, Protestantism on the singular. But authentic human existence demands that equal meaning and value be given to both singular and plural, all three persons, and all three genders. Thus, Protestantism is correct in affirming that the We are of society expresses a false identity unless each of its members can say I am; Catholicism correct in affirming that the individual who will not or cannot join with others in saying We does not know the meaning of I.
