What theologians say "sensu sci (scilicet?) formali"

[NaphtaliPress]

From Durham's commentary on Revelation; what common place or perhaps place in the scholastics, Aquinas, does this have reference to? See bolded text below. I'm getting very little on the short phrase sensu sci (scilicet?) formali.
7. When the Mediator is thus worshipped, there is no distinct Object of Divine Worship worshipped: but as whatever Person be named, it’s the same God; so, however the Mediator be named, or considered, it’s the same Person: for, though the second Person of the Godhead, considered in Himself, be not unum, or, the same thing with the Mediator, (sensu sci-formali, as Divines say) yet is He Vnus, the same Person; and the second Person of the Godhead, being Vnum, to wit, the same God with the other two glorious Persons essentially considered, although He be not Vnus with the Father and Spirit, considered personally: for, the Godhead, essentially taken, is the same thing with the Father, Son and Spirit, as hath been said.

Maybe here; Durham had previously referenced this same chapter and this is the subject in question. Voetius, Sel. Disp. v. 1. p. 522.

I suspect you are right that "sci" is short for "scilicet;" elsewhere it is abbreviated sc. or scil. ("Sc. provides a parenthetic clarification, removes an ambiguity, or supplies a word omitted in preceding text, while viz. is usually used to elaborate or detail text which precedes it.")

"sensu formali" is contrasted with "sensu identico" elsewhere (e.g. by John Bradock). Not sure if that helps or not.
