Pre Vatican II missals are available and recommended as the Extraordinary Form of the Mass is making a comeback due to the return to orthodoxy that is needed. A 1962 Catholic Missal is available from Amazon or any Catholic bookstore. The Church being more orthodox may make some upset, but at some point being less orthodox leads one to perdition. Where that point is I don’t know, I just don’t want to be too close to it. More reverence in the worship service, like the Latin Mass, is a good thing.
The rejection of the deutero-canonical books is like the rest of the Churches “not in union with Rome” doctrine. One day approved, the next day rejected. Abortion, birth control, divorce, are not doctrines applied to the teaching of the revealed Word of God but what the majority of the people want to do at a given time. Pray for them.
