Korey Maas (Lutheran), Miles Smith (Anglican), and D. G. Hart (Presbyterian) do their impersonations of evangelicals and give their testimonies in this episode.  That's a way of saying they describe the biographical route by which they came to Lutheran, Anglican, and Presbyterian churches, respectively.  Spoiler alert: theology is important (even for Anglicans).  Related: education and catechesis are also important.  What may be surprising is the influence that Francis Schaeffer had on three American Protestants, in different communions, who became adults in different decades, while living and pursuing academic degrees in different regions of the United States.  A question unanswered is the degree to which these stories are characteristic of cis-gender men or whether they might also apply to women.
