Heidegger's Bible Handbook: NT Apocrypha: The Liturgy of St. Mark
13. And to Mark, the νοθεία/illegitimacy of which is added.
The Liturgy of Saint Mark is no more genuine, which, edited by Cardinal Sirletus, is extant in Bibliotheca Patrum, Tome 6, Edition 3, and is cited by Gregory of Valentia, Coccius, and others, to cover with an ornamental layer the deliria of today’s Mass. But that makes mention in the collect, or συναπτῇ, of the crowning of Mark with martyrdom. How then was Mark himself able to write it? Also, prayer is offered for all orthodox Bishops, Presbyters, Deacons, Subdeacons, Lectors, Cantors, and Laics, which orders of ministers were certainly completely unknown to Saint Mark. I pass over in silence altogether plain vestiges of more recent superstition, with which this liturgy also is more than a little contaminated.
 Guglielmo Sirleto (1514-1585) was Italian Cardinal, scholar, and linguist. He served as custodian of the Vatican Library, and was an expert on the Greek manuscripts therein.  Gregorius de Valentia (1549-1603) was a Jesuit scholar, originally from Spain. He served as Professor of Theology at Dillingen (1573-1575) and at Ingolstadt (1575-1592).  Jodocus Coccius (1581-1622) was a German Jesuit, and Professor of Theology at Molsheim in Alsatia.
