Hello all,

I have been using some of the sources on this website for Communion Antiphons when I want to do something a little deeper than the SEP, which I use every week. I noticed that the Communion Antiphon I'd like to do is actually the English version of what is sung at the Extraordinary Form on Corpus Christi (which would actually be tomorrow, I guess...)

Anyway, I don't have access to a Graduale or a Liber - am I able to use this Communion Antiphon in place of what you'd find in the SEP, for example? It's the text that ends with with St. Paul's adominition that "whoever unworthily partakes in the Body and Blood of the Lord is guilty of the Body and Blood of the Lord", etc...
