St Michael, Come to Our Aid

I must recall to pray St Michael more often, that that blessed Archangel intervene for the people of God, as once the prophet Daniel saw him do, and may thrust down to Hell Satan and all evil spirits.

Here are some collects from his Vespers according to the Ambrosian Rite; I haven't quite finished translating the last one:

Oratio I

Da nobis, omnipotens Deus, beati Michaelis Archangeli honore ad summa proficere: ut cujus in terris gloriam prædicamus, ejus quoque precibus adjuvemur in cœlis. Per…

Give to us, almighty God, to profit to the utmost by honouring blessed Michael the Archangel: that as we tell of his glory on earth, we may be helped by his prayers in heaven. Through…

Oratio II = Roman

Oratio III

Adesto plebi tuæ, misericors Deus: et ut gratiæ tuæ potiora beneficia percipiat, beati Michaelis Archangeli fac supplicem deprecationibus sublevari. Per…

Be present to thy people, merciful God: and that they may perceive greater benefits by thy grace, make them, prostrate in prayer, to be lifted up by the prayers of blessed Michael the Archangel. Through…

Oratio IV (cf. Roman Postcommunion)*

Beati Archangeli tui Michaelis interventione suffulti, supplices te, Domine, deprecamur: ut, quos honore prosequimur, contingamus et mente. Per…

Supported by the intervention of thy blessed Archangel Michael, bowing low, Lord, we pray thee: that, those we accompany with honour, we may lay hold of with our mind. Through...

* There seems something strange here: the Roman recension reads intercessione not interventione, a merely verbal difference, but also reads not quos honore but quod ore – and the meaning seems quite cryptic in both cases.  Help!

And furthermore: glancing at Dominican Vespers of St Michael, what did I see but that the Magnificat antiphon was all but identical to the Ambrosian Collect IV above (excluding the Per Dominum &c. of course), excluding only the words Beati and tui and supplices, and adding an alleluja.  Hmm, all very interesting...
