As it was St. James (early Church) that promulgated the use of oil .....then it is the Church that can modify it. 

Do you not understand that St James' description of Extreme Unction is
a) in Scripture (which means it's infallible)
b) Apostolic Tradition = infallible

I think you don't understand what Apostolic Tradition is.  You keep arguing that Apostolic Traditions are changeable.  But they aren't.

Not only do you deny that Apostolic Tradition is infallible (ie unchangeable), you also deny it even exists?  Wow

Both you and Boru are conflating terms.  You say olive oil is from Apostolic AND ecclesiastical authority.  ??  It cannot be both.  Apostolic authority = from Christ, which cannot change.  Ecclesiastical authority = Church decision, which can change. 

Boru says that Paul6 admitted that olive oil is from Scripture (ie Divine origin) but then says Paul6 is allowed to change it because the Church decided it.  ?? 

Either olive oil is:
1.  From Scripture (which it is)
2.  From Scripture/Apostles (yes)

or

3) the church decided on Her own.

If you say 1 or 2, then this means it is DIVINELY CREATED, which means it cannot be changed. 

If Scripture is involved, it’s unchangeable.  If Apostolic authority is involved, this is part of Divine Revelation, and is unchangeable.

The Church can “declare, teach, decide” that something is Scriptural or Apostolic, but that doesn’t mean She can change it.  She can only change things which are of human origin (ie canon law, some feast days, etc).

Olive oil is proper and ordinary matter because of Apostolic usage and ecclesiastical prescription, but it is not part of the divine institution of the sacrament itself. As +Pius XII teaches, 'The Church has no power over the substance of the sacraments… but the Church does have power over those things which it has established' (Sacramentum Ordinis, 42).

This means that the Church can prescribe olive oil as the ordinary matter, but in necessity she can allow another vegetable oil without affecting the sacrament’s validity. Apostolic practice establishes olive oil as proper and traditional, not as essential or divinely mandated. Therefore, the Church’s authority to regulate ordinary matter does not contradict Scripture or Apostolic tradition, and olive oil’s changeable nature in necessity is fully consistent with Catholic doctrine.

This principle illustrates why the Novus Ordo Mass and sacraments are a source of positive doubt. By altering traditional rites, formulas, and even proper or ordinary matter, the Novus Ordo departs from what the Church has always prescribed. In doing so, it directly violates +Pope Pius V’s decree in Quo Primum (1570), which commands the faithful to retain the Roman Missal unchanged. These innovations introduce uncertainty about whether the essential elements instituted by Christ are preserved intact, making every Novus Ordo sacrament potentially doubtful. Any claim to certainty in its validity ignores both the teaching of +Pius XII and the immutable law of +Pope Pius V. The Novus Ordo is therefore objectively and positively doubtful, and faithful Catholics must exercise prudence and adhere only to the sacraments that safeguard Christ’s institution without compromise.

You really have a block on this one. The precise Form and Matter of Baptism and Holy Eucharist were given to us directly from Christ. He then conferred His power and authority to St. Peter, the Pope. The precise Form and Matter on the other five sacraments were promulgated by the apostles (the Church) after this transferal of power. They are our direct source. As Christ can change His own laws, so too can the "Christ" of Rome change his own laws.

Yeah Boru, Pax is 100% right. You need to realize that all of Scripture is Divine Revelation, and that each Apostle was individually infallible. You even quoted the infallible teaching from Trent: "...In which words, as the Church has learned from apostolic tradition, received from hand to hand, he (St. James) teaches the matter, the form and proper minister, and the effect of this salutary sacrament." Ref: 'On the Sacrament of Extreme Unction, 14, second session.

So if you believe what the Church teaches, if you believe what you posted, then you also admit that the "matter, the form and proper minister" is from God through from St. James the Apostle. The matter, form and minister of the sacrament was not something any pope established, those are from God, received from hand to hand from that day till PPVI. 


 

I can give you Trent: "Now, this sacred unction of the sick (note the wording) was instituted by Christ (and) recommended and promulgated to the faithful by James the apostle (early bishop of the early Church): "Let him bring in the priests of the Church, and let them pray over him, anointing him with oil, in the name of the lord: the prayer of faith shall save the sick man; and the Lord shall raise him up: and if he is in sins, they shall be forgiven him." (Note: the words of James the Apostle, not Christ). In which words, as the Church has learned from apostolic tradition, received from hand to hand, he teaches the matter, the form and proper minister, and the effect of this salutary sacrament." Ref: 'On the Sacrament of Extreme Unction, 14, second session.

Trent makes clear that the Matter and Form was promulgated by James the Apostle, a bishop of the Church. We have no precise Matter or Form from Christ as we do for Baptism and Holy Eucharist. We rely on the Church for this mandate.

In the Book of James (James 5:14), the word translated as "oil" (in the Trent quote) is the Greek word for OLIVE OIL specifically: elaion (ἔλαιον).

P.S. And if you think that olive oil was the only oil around the Holy Land, then you would be mistaken. Palm oil (and possibly other oils) had been used by humans in that period.

Yes, we have established that. It was the native oil at the time. That this oil effected a Sacrament in conjunction with the From was promulgated by St. James. Our source for this sacrament is him, a bishop of the Church.

Olive oil is proper and ordinary matter because of Apostolic usage and ecclesiastical prescription, but it is not part of the divine institution of the sacrament itself. As +Pius XII teaches, 'The Church has no power over the substance of the sacraments… but the Church does have power over those things which it has established' (Sacramentum Ordinis, 42).

This means that the Church can prescribe olive oil as the ordinary matter, but in necessity she can allow another vegetable oil without affecting the sacrament’s validity. Apostolic practice establishes olive oil as proper and traditional, not as essential or divinely mandated. Therefore, the Church’s authority to regulate ordinary matter does not contradict Scripture or Apostolic tradition, and olive oil’s changeable nature in necessity is fully consistent with Catholic doctrine.

Apostolic Tradition is SEPARATE from church authority.  That’s the part you’re missing.  

Apostolic Tradition = divine revelation = from Christ, who instructed the Apostles.  This is infallible and unchangeable.  

After the Apostles died, THEN we have 100% church authority.  

You guys keep ignoring Apostolic Tradition's unique status. 

So, as Boru has repeatedly argued, there are only 2 types of Catholic authority:

1.  Christ/Scripture.
2.  Church authority - which can be changed, by any pope.
3.  Tradition - this is simply another form of Church authority, which can be changed.

So according to her, any church council can be changed.  Trent can be changed.  The dogmas of the immaculate conception and the assumption can all be changed, because the Church can change anything that She originally ruled upon.

Wow.
