Italian to English Art/Literary Religion critique of Christian painter

This is the first phrase in a critique of the paintings of the Leccese painter Giuseppe Afrune. Unfortunately, there is no syntactic context.
Not being a Christian, but very spiritually minded, this is a rather challenging text for me!

I notice that "Urgenza della verità" gets 95,000 hits while the lieral translation "Urgency of truth" get just one!!!
What does this phrase actually mean in Italian and is there in fact an equivalent phrase in English?

ORIGINAL: "Gesù. ‘Il tuo volto, Signore, io cerco’
Urgenza della verità. Calore di un’accoglienza misteriosa, irripetibile, universalmente costituita, storicamente determinata, riconoscibile nell’unicità della persona del Figlio dell’Uomo.

TRANSLATION FIRST DRAFT
Jesus. ‘It is your face, Lord, I am looking for’

The urgency of truth. That warmth we feel, arising from a mysterious, unique, universal welcome, one that is historically determined, that we recognise exclusively in the person of the Son of Man.

Incidentally, I'd also be interested if you have any suggestions or comments on how I could improve the first draft of the translation
