Ave vivens hostia

Does anyone here sing Ave vivens hostia? If so, to which tune? I'd like to sing it to a Gregorian chant hymn tune, but I suppose I could settle for PASSION CHORALE if I had to. The meter is 76 76 D, the text is:

1. Ave, vivens hostia,
    Veritas et vita,
    In qua sacrificia
    Cuncta sunt finita,
    Per te patri gloria
    Datur infinita,
    Per te stat ecclesia
    Iugiter munita.

2. Ave, vas clementiae,
    Scrinium dulcoris,
    In quo sunt deliciae
    Caelici saporis,
    Veritas substantiae
    Tota salvatoris,
    Sacramentum gratiae,
    Pabulum amoris.
 
3. Ave, manna caelicum
    Verius legali,
    Datum in viaticum
    Misero mortali,
    Medicamen mysticum
    Morbo spiritali,
    Morte dans catholicum
    Vitae immortali.
