Can someone, please, explain which date is the relevant one, to determine the version of liturgy of the missal?
Most missals display four different dates for:
1. Imprimis potest: 1962
2. Imprimatur: 1962
3. Copyright (C): 1958, 1962 by Abbaye of ...
or:
1. Imprimis potest: 1964
2. Imprimatur: 1965
3. (C): 1965 Abbaye de St ...
4. (C): 1960 Darton ...
or:
1. Imprimis potest: 1962
2. Imprimatur: 1962
3. (C): 1960 Abbaye de St ...
4. (C): 1960 Darton ...
etc., etc..
My objective is to buy a missal that conforms, exactly, to the 1962 liturgy. Kindly, could some one help me understand?
