St Robert Bellarmine’s Commentary on Psalm 117
Posted by Dim Bulb on January 22, 2017
All nations are called upon to praise God for his mercy and truth
1 He addresses the whole Church, and exhorts it to praise God. “All ye nations” is directed to the converted gentiles, who are named first by reason of their being in the majority, and the people nearer those of the Jews who had been converted to the faith; and the Apostles themselves, in alluding to a similar expression in the second Psalm, “Why have the gentiles raged, and the people meditated vain things,” apply the former to the gentiles, and the latter to the Jews.
2 The reason assigned for praising God is, “for his mercy is confirmed on us,” by the arrival of the Messias to Jews and gentiles; “and the truth of the Lord remaineth forever;” for the Church was established, “Against which the gates of hell shall not prevail,” and his kingdom was established, of which there will be no end.
