Patristic Quote of the Day

So everything which we esteem holy proclaims that Sole Holiness. Cherubim and Seraphim with unwearied voices praise Him and say: Holy, Holy, Holy, is the Lord God of Sabaoth. Isaiah 6:3 They say it, not once, lest you should believe that there is but one; not twice, lest you should exclude the Spirit; they say not holies [in the plural], lest you should imagine that there is plurality, but they repeat thrice and say the same word, that even in a hymn you may understand the distinction of Persons in the Trinity, and the oneness of the Godhead and while they say this they proclaim God.—St. Ambrose, On the Holy Spirit, Book III, chapter 16
