sicut i.icelo [?] tre[s] sunt pat[er] & uerbu[m] & sps [=spiritus] scs [=sanctus] & tres unum sunt.

So (translation:) "....three are the father and the word and the holy spirit and the three are one." Immediately above this Comma, we find in the left column

17
omnis qui credit quo[niam] ihs [=Iesus] e[st] xps. [=Christus]
ex do [=domine] natus e[st] & omnis qui dili

which is the beginning of 1 Joh 5:1 from the Vulgate "1 omnis qui credit quoniam Iesus est Christus ex Deo natus est et omnis qui diligit eum qui genuit diligit eum qui natus est ex eo"
