The Council of Florence taught that the passing of the chalice and patten, the tradition instrmentorum, was part of the matter of Holy Orders. This was part of the matter for centuries in the Latin rite. Pope Pius XII changed this and the matter for Holy Orders. Using his authority and that of the Church to change the matter and form for the five sacraments that the Church has the right to change, Pius XII ruled that now the matter for Holy Orders was merely the laying of hands.
Apostolic Constitution Of Pope Pius XII on the Sacrament of Order November 30, 1947 Sacramentum Ordinis:
"#4 Wherefore, after invoking the divine light, We of Our Apostolic Authority and from certain knowledge declare, and as far as may be necessary decree and provide: that the matter, and the only matter, of the Sacred Orders of the Diaconate, the Priesthood, and the Episcopacy is the imposition of hands; and that the form, and the only form, is the words which determine the application of this matter, which univocally signify the sacramental effects - namely the power of Order and the grace of the Holy Spirit - and which are accepted and used by the Church in that sense. It follows as a consequence that We should declare, and in order to remove all controversy and to preclude doubts of conscience, We do by Our Apostolic Authority declare, and if there was ever a lawful disposition to the contrary We now decree that at least in the future the traditio instrumentorum is not necessary for the validity of the Sacred Orders of the Diaconate, the Priesthood, and the Episcopacy"
