Theologicae regulae
Alan of Lille (1120–1202)
Alan's theological rules, wherein he sets forth over a hundred concise maxims.
Prologus I: Theologicae regulae
Regula I: Monas est, qua quaelibet res est una.
Regula II: In supercoelesti unitas, in coelesti alteritas, in subcoelesti pluralitas.
Regula III: Monas gignit monadem, et in se suum reflectit ardorem.
Regula IV: In Patre unitas, in Filio aequalitas, in Spiritu sancto unitatis aequalitatisque connexio.
Regula V: Sola monas est alpha et omega sine alpha et omega.
Regula VI: Omne limitatum alpha et omega aut est bonum ab alpha, aut est bonum ab alpha et omega.
Regula VII: Deus est spaera intelligibilis, cujus centrum ubique, circumferentia nusquam.
Regula VIII: Deus est cui quidlibet quod est, est esse omne quod est.
Regula IX: Quidquid est in Deo, Deus est.
Regula X: Omnis praedicatio de Creatore facta, copulata est atque conjuncta.
Regula XI: Omne simplex esse suum, et id quod est, unum habet.
Every simple thing is its own being, and what it is, it has as one.
This rule descends from that one: God is one for whom whatever he is, etc. The sense, then, is: Every simple thing, etc., that is: if anyone should say simply, of that which is truly simple, is, as, God is, and should say: God is something, as, God is great, or strong: no one ought to understand that something different is predicated in the second proposition than in the first, so that if it is said of the Father, or of the Son, or of the Holy Spirit, is, nothing else is predicated than when it is said: the Father is powerful, the Son is powerful, the Holy Spirit is powerful; but altogether the same thing: by no reasoning ought it to be understood that what he is, is one thing, and that by which he is powerful, another, since for the Father, and the Son, and the Holy Spirit it is altogether the same to be, and to be powerful.
