Archie is uncomfortable with Edith's new friend, a peppery Catholic nun named Theresa (Phyllis Avery). When Edith begins attending mass -- mainly to hear the music -- Archie worries that his wife is planning to convert to Catholicism. In his usual roundabout manner, Arch holds next-door neighbor Irene Lorenzo for leading Edith "astray." Written by Ray Taylor and Don Nicholl, "Edith's Conversion" originally aired on November 10, 1973. ~ Hal Erickson, Rovi
