Because the Flagstons are a a stereotypical upper-middle class family living in the suburbs in what appears to be the ’50s or first half of the ’60s, I’ve always assumed they’re Episcopalians. The Episcopal Church has a page on their website that says they believe in justification through faith, though they don’t use the “faith alone” formula, and anyway, even the most hardcore Calvinist sees good works as flowing naturally from true faith. Nice try pushing antinomianist heresy, Ditto!
