"Secondly, the fact that the use is "extraordinary" must not mean that it should be used only by priests and faithful who adhere to the extraordi-nary form. As Father Bux proposes, it would be very positive if someone who usually celebrates in the "ordinary" form would also, "extraordinarily", do so in the "extraordinary" form. This is a treasure that is the heritage of all and to which, in one way or another, everyone should have access. Therefore one could propose it especially for occasions when there is some particular rich-ness of the old missal of which one could benefit (especially if in the other calendar there is nothing special foreseen): for example, for the time of Septuagesima, for the four Embertides or for the Vigil of Pentecost, and maybe even in the case of certain special communities, both of consecrated life and of brotherhoods or fraternities. Celebrations in the "extraordinary" form would also be of great usefulness for the offices of Holy Week, at least some of them, because all the rites preserve during the Sacred Triduum ceremonies and prayers that go back to the most ancient times of the Church."
