Apolytikion, Tone 1
The shepherd’s pipe of thy theology/ conquered the philosophers’ trumpets;/ for since thou didst search out the depths of the Spirit,/ beauty of speech was added to thee./ Intercede with Christ our God that our souls may be saved,/ O Father Gregory.
Kontakion, Tone 3
With thy theologian’s speech thou didst dispel the philosopher’s cobwebs,/ O glorious Gregory;/ and thou dost adorn the robe of Orthodoxy woven for the Church from on high./ Wearing this, she cries out with us thy children:/ Rejoice, O Father, most excellent mind of theology.
Although the Pope is describing St. Gregory in this passage, from what I have read about Benedict XVI, it describes himself as well.
Long time no see....
