What do you mean by "type"? The matter is the matter and the form is the form for each sacrament. These are essential to the sacraments, as taught by Florence. Meaning the sacrament does not exist without them. Christ instituted all of the sacraments, as taught by Trent. Therefore, Christ defined the matter and form for each sacrament, as there is no sacrament without matter and form. When Christ instituted the sacraments requiring holy oils as matter, He defined what oil to be used..because that is essential to the sacrament.
There is no simpler way to put this. What do you not understand?
You are unable to provide any evidence that the Church either, A) decided one day to use exclusively Olive oil, or B) ever used any oil other than olive oil. This is because the Church has always taught that olive oil is required for holy oils. That is called Tradition. That is Divine Revelation. This is because the sacraments were divinely instituted by Christ, and not the Church, and the Church has always upheld what Christ taught and established
Christ instituted the seven Sacraments. Agreed. Now you state "Christ defined the matter and form for each sacrament." So, what I'm asking is, if CHRIST defined the Matter and Form of all the sacraments, may I have the scriptural references to all these Matter and Forms. Don't worry about Baptism or Holy Eucharist because I already know these; just the other five.
With regards to Olive Oil: There is no doubt that the Church always used olive oil for Holy oils and has decreed that this is the oil to be used in Sacraments. Pope Paul VI states this to be so himself. So this is not the argument;
Pope Paul VI did not discard Olive Oil. Nor did he teach that another oil could be willy-nilly used instead. The debate arises because Pope Paul inserted an
exception to the rule that if Olive Oil cannot be found, a another plant-based oil could be used in the case of necessity.
Yet, without clarifying that this was an exception to the rule, Fr. Hesse implied that Pope Paul changed the use of olive Oil to vegetable oil - which is outrageously misleading if not a bold faced lie - and that this change of oils rendered the sacrament invalid.
So the million dollar question is: does this exception to the rule, as instituted by Pope Paul VI, render the sacrament invalid as Fr. Hesse claims?
In James 5:14-15 it reads: "Is any man sick among you? 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. And the prayer of faith shall save the sick man: and the Lord shall raise him up: and if he be in sins, they shall be forgiven him." Clearly this a template for Extreme Unction however the exact matter and form are not specified. It alludes to oils, but it was the Church that decided that these oils (and yes, St. Thomas Aquinas states this meant olive oil) would actually confer the sacrament via the Form.
It was the Church that "fixed" (commanded) the Matter and Form. Pope Pius XII teaches in Sacramentum Ordinis the principle: "Ecclesiam quod statuit etiam mutare et abrogare valere - that which the Church has established she can also change and abrogate." This Pope further explained that where the instruments of the matter are determined by the Church, they can be changed. This is supported by his changing of the matter in Holy Orders that had been set down by the Council of Florence - he declared that the only Matter necessary was the imposition of the hands, and that the passing of the Chalice - traditio instrumentorum - was no longer required.
Emphasizes Pius XII speaking of the Matter: "If it was at one time necessary, even for the validity by the will and command of the Church, everyone knows that the Church has the power to change and abrogate what she herself has established." SO, 42.
Where the Council of Trent teaches that the Church has no power to change "the substance of the sacraments" it means that the Church cannot change the Form and Matter of what Christ precisely instituted via Divine Revelation (Scripture and Sacred Tradition).
