I guess that this is a poem by elder Joseph of Vatopaidi, called: "Hymn to the Holy Trinity".

 

[aprilka]

Can you tell me the tone ?

 

[goldengreek25]

I believe it's based on Plagal of the 4th, though they transition in and out of other tones, including Plagal of the 2nd.

 

[EIRYK EMNOSHELE]

I have an apology to make to you. This isn't the holy trinity hymn.
Sorry, I haven't any other info other than they are praising a man who lived a very ascetic life.
