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.
Whatever is in God, is God.
That is, whatever term in natural things predicates inherence, in God predicates essence. Now such universality, when it is said: Whatever is in God is God; or, Whatever it is that it is, etc., does not refer to a plurality of things signified, but of signifiers and effects; for the effects of one and the same cause are diverse, signified by diverse names, when it is said: God is strong, pious, prudent. There is, therefore, universality in speaking, in effecting, but singularity in being.
