The modernized Missal promulgated by Angelo Roncalli/John XXIII in 1961 and 1962 was meant of its nature to be transitory, and that it is precisely what it turned out to be, a transitional bridge between the Missal of 1958 that been approved, so we are told, by the dying Pope Pius XIII on October 3, 1958, six days before his death, and that of some future liturgy conceived to be that veritable Trojan Horse mentioned just above into which could be loaded one Modernist presupposition after another, not the least of which is the belief that everything about the Faith (doctrine, liturgy, morals, Scripture studies, pastoral life) is in flux, in evolution, if you will.
