Lyrics:
Ean tes gloses ton anthropon lalo ke ton angelon
agapin de mi eho, gegona halkos ihon i cymbalon alalazon.
Ke ean eho profitian ke ido ta mystiria panta
oste ori methistanin,agapin de mi eho
ouden imi.
I agapi makrothymi, christevete,
I agapi ou zili, i agapi ou perperevete, ou fysioute.
Panta stegi, panta pistevi, panta elpizi, panta ypomeni,
i agapi oudepote ekpipti
ite de profitie katargithisonte
ite glose pafsonte
ite gnosis katargithisete
Nini de meni, pistis, elpis, agapi,
ta tria tafta,
mizon de touton i agapi.
