Boru,
In the last part of the Aquinas quote (that you provided), he says the following:
Aquinas, using the testimony of Dionysius, says that the use of Chrism (i.e., olive oil mixed with balsam) for the "matter" came from the Apostles themselves. That agrees with what we have been telling you. The "matter" of the Sacrament was instituted by the Apostles. Anything the Apostles did, in that regard, is considered to be infallible because it is part of Sacred Tradition. The Church cannot change that because "the Church" did not institute it. The Apostles instituted that.
I have already told you what Pope Eugene meant, so I will not go back into that in detail. Pope Eugene was speaking of a change in nomenclature, not a change in the "matter."
Yes, the use of a chrism using olive oil was instituted by the Apostles. My very point. The Apostles are the Church. The Church decided that instead of laying on the hands
.Summa - St. Thomas Aquinas - ConfirmationIn like manner, too, when the
apostles imposed their hands, and when they preached, the fulness of the
Holy Ghost came down under visible signs on the
faithful, just as, at the beginning, He came down on the
apostles: hence Peter said (
Acts 11:15): "When I had begun to speak, the
Holy Ghost fell upon them, as upon us also in the beginning." Consequently there was no need for sacramental sensible
matter, where
God sent sensible signs
miraculously.
However, the
apostles commonly made use of chrism in bestowing the
sacrament,
when such like visible signs were lacking. For
Dionysius says (Eccl. Hier. iv): "There is a certain perfecting operation which our guides," i.e. the
apostles, "call the sacrifice of Chrism."
Who decided to do away with the laying of hands in Confirmation altogether? Obviously the Church decided.
States the Council of Florence:697 "Now, when the apostles, who were in Jerusalem, had heard that the Samaria had received the word of God, they sent unto them Peter and John. Who, when they were come, prayed for them that they might receive the Holy Ghost. For He was not as yet come upon any of them: but they were only baptized in the name of the Lord Jesus.
Then they laid their hands upon them; and they received the Holy Ghost" [Acts 8:14 ff.].
In place of this imposition of hands confirmation is given in the church."Angelus, you read it which way you like - both ways mean the same - changing the name clearly means that that laying of hands was no longer relevant for validity. Stop being pedantic. There is absolutely no doubt that the early matter, the imposition of hands, was replaced (in place of) by a more formal formula involving chrisms (olive oil/baslam).
