A liturgical update in Rufinus' translation of Origen's Commentary on Romans?

[Extract] ...linguistic clarifications can often be easily recognized and other non-doctrinal additions from Rufinus can also be identified with varying degrees of plausibility, insofar as they too appear to fit better in his context at the turn of the fifth century than in Origen's early third-century context. In what follows, I will argue for one such intervention (possibly two) on the part of Rufinus, updating a brief discussion of baptism to speak to the mystagogical practice contemporary with the translator.
