20 Nor should anyone think that this use of the original texts, in accordance with the methods of criticism, in any way derogates from those decrees so wisely enacted by the Council of Trent concerning the Latin Vulgate. It is historically certain that the Presidents of the Council received a commission, which they duly carried out, to beg, that is, the Sovereign Pontiff in the name of the Council that he should have corrected, as far as possible, first a Latin, and then a Greek, and Hebrew edition, which eventually would be published for the benefit of the Holy Church of God. If this desire could not then be fully realized owing to the difficulties of the times and other obstacles, at present it can, We earnestly hope, be more perfectly and entirely fulfilled by the united efforts of Catholic scholars.
