Lex Orandi, Lex Credendi.

I had not reflected enough upon the classic significance of "lex orandi, lex credendi." By then, to me the liturgists were technicians and choreographers rather than the pure scholars who studied texts in various languages. I distinguished "liturgists" from "liturgiologists". In this reckoning, Robert Hovda was a liturgist, and Josef Andreas Jungmann was a liturgiologist. One was not serious, while the other was. True, the older generation of pastor-liturgists such as Martin B. Hellriegel in St. Louis had fostered a noble movement. But the next generation of liturgists presented themselves to us, when we were much younger than they and eagerly watching, with a peculiar affinity for fastidious liturgical aestheticism coupled with a deep hatred for the old rites and devotions.
