“Holy and fearful is His Name” (Ps. 110:9), that is, it is worthy of wonder and awe... And in what way is His Name holy and fearful? Demons are in fear of it and illnesses flee from it. With this Name the Apostles conquered the whole universe; David was victorious over the alien using it instead of a weapon; by means of it are done many mighty deeds; by means of it we perform the Mysteries. Considering, therefore, how many wonders His Name achieves, how many benefits, how it confounds His opponents, how it gives security to Hos own, and pondering the things that surpass natural logic and defy human reason, he says "holy and fearful is His Name." And if it is holy, it requires holy mouths for singing praise, holy and pure.
St. John Chrysostom, Commentary on Psalm 110
