Tuesday of Holy Week
The Collect for Holy Tuesday merits special attention. The dominicis passionis sacramenta are the sacred signs and rites by which the mystery of the Lord's Passion is made present in an efficacious manner. The Collect uses the word peragere, which means, among other things, to carry out, to enact, or to perform. It is by worthily carrying out the sacred liturgy that the fruit of the Passion of Christ is communicated to our souls, that is, the pardon of our sins.
Omnipotens sempiterne Deus,
da nobis ita dominicae passionis sacramenta peragere,
ut indulgentiam percipere mereamur.
Per Dominum nostrum Iesum Christum Filium tuum,
qui tecum vivit et regnat in unitate Spiritus Sancti,
Deus, per omnia saecula saeculorum.
The Marquess of Bute gives this:
O Almighty and everlasting God,
give us grace so to use the solemn and mysterious memorial
of the Lord's Suffering,
that the same may be unto us
a means whereby worthily to win Thy forgiveness.
Through the Same our Lord Jesus Christ Thy Son,
Who liveth and reigneth with Thee,
in the unity of the Holy Ghost,
one God, world without end.
Note that he renders "dominicis passionis sacramenta" as "the solemn and mysterious memorial of the Lord's Passion."
Monsignor Knox offers a translation that is, at once, succinct and poetic. For "dominicis passionis sacramenta" he gives, "this showing forth of the Lord's Passion."
So pass we, O God eternal,
through this showing forth of our Lord's Passion,
that we may win his gift of pardon.
Through the same Jesus Christ, thy Son, our Lord,
who is God, living and reigning with thee,
in the unity of the Holy Spirit,
forever and ever.
And here is my own attempt:
Almighty and eternal God,
grant that we may so carry out
the sacred rites of the Passion of the Lord
as to be found worthy of your gracious pardon.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
God forever and ever.
