Miss Brodie defies Calvinism but also absorbs it, as Sandy perceives: she just usurps God’s role in the Calvinist scheme by electing herself to grace, to a godlike role. Sandy wishes that she, too, could take Calvinism seriously, so that she could in turn have something to react against. Instead, she reacts against Miss Brodie, resulting later in her conversion to Roman Catholicism, a religion in which one’s earthly conduct matters in whether one attains heaven.
