For the latter purpose it would be helpful to have associated (psalm) texts to amplify the antiphon, (if we want to take up the idea) .The entrance and communion antiphons of the Missal were intended to be recited, not sung, and to inspire the creation of suitable songs in the vernacular.

I would expect that the addition to the US GIRM permitting/encouraging singing of the Missal antiphons does not extend to singing them in Latin, since IGMR does not include this change.
