I am very confused by the article. Maybe if I would have been there, I would understand the point. Since the Lutheran liturgy is very similar to the liturgy found in the Book of Common Prayer, and the ELCA and the Episcopal Church are in full communion with each other, I don’t understand the sentiment behind the thought that celebrating the Lutheran liturgy at an Episcopal seminary felt out of place (leading to the author’s unfortunate implication that the service felt like a “show” instead of worship). I’ve been to several Episcopal worship services, and always felt at home (as long as the celebrant sticks to the rubrics instead of doing some of the wacky things some Episcopalians do these days).
Also, as a side note, the author is uncomfortable with the word “mass” to describe Lutheran worship. However, the Confessions state: “we do not abolish the Mass but religiously keep and defend it” (Augsburg Confession Article 24). Moreover, Luther’s two primary orders of worship were called the “Formula Missae” and the “Deutsche Messe”, indicating an obvious willingness to retain the term.
