What is the "mystery of faith"?

[savedbychrist]

In the Tridentine Mass, it seems to be referring to transubstantiation, since it follows “this is the Chalice of my Blood, the Blood of the new and eternal Covenant”, describing that the cup of wine is about to become the Chalice of Blood mysteriously. But in the Novus Ordo Mass, it refers to the Passover of Jesus, since it is followed by “we proclaim Your death, O Lord, and profess Your resurrection, until You come again”. (This one is more certain, since before the update in translation, it is the reply of “let us proclaim the mystery of faith”.)

So what exactly is the mystery of faith here? Or was the meaning indeed changed in 1969?

 

[BartholomewB]

I think it’s the same in both cases.

The priest announces, “The mystery of faith” because the consecration has made a tremendous change in the celebration. This mystery is not like something out of Agatha Christie, a puzzle to be solved, but a reality that we accept in faith because we cannot possible comprehend it just by reason.

[Tis_Bearself]

The mystery of faith is the consecration of Christ’s Body and Blood (transubstantiation). The meaning never changed. Also, the business about “we proclaim your death…” is only one of (currently) three possible acclamations (used to be four until the OF was revised to eliminate one).

Here is a discussion.

[Genesis315]

That’s why the “let us proclaim…” was a bad translation. It’s not in the Latin. The mystery of faith is the consecration and more specifically the Blessed Sacrament itself. My understanding is in the very ancient liturgies, “mysterium fidei” was said by the deacon aloud during the consecration, either like we ring the sanctus bells (both of these were more important with the quiet canon) or as a warning to catechumens and others that the sacrament was not for them, but only the baptized faithful. Overtime it ended up being worked into the actual words of consecration probably due to situations with only one minister presiding without a deacon.

 

[po18guy]

In a broad sense, and indicting no one: There is a spirit of division running free in the Church. It seeks to divide where no division exists. It seeks to demand “either this…or that” when in truth the faith has always been “both this and that.”

It questions long ago settled points and seeks always and everywhere to divide and rule by confusion. This spirit was spoken of in Genesis 3.

The antidote is humble submission and unity by the Holy Spirit and His gift - free for the asking - of understanding, one of the 7 gifts of the Holy Spirit.
