Jag tror att du är korrekt. Så gör MASH wiki:
In many episodes, Mulcahy is seen wearing a "Loyola" hoodie. This makes sense in that Mulcahy was a Jesuit and Loyola is a Jesuit school. In the final episode of the series, however, Mulcahy is seen wearing a "Wesleyan" sweatshirt; Wesleyan University, the alma mater of actor William Christopher, was affiliated with the Methodist Church until 1937.
Han identifierar också sig själv som en jesuit i serien men jag kan inte hitta specifika säsong-episod citat.
