Now that we have demonstrated that God is infinite, we begin to inquire about infinity found in other things, or, better yet, whether infinity can be found in other things.
This article aids up in being able to distinguish that which is absolutely (simpliciter) infinite (which is God alone) from that which is relatively (secundum quid) infinite (which are many things besides God). The former infinity is absolute in its perfection since it is based on the actuality of God (i.e., an infinite form not limited by the imperfection of matter), whereas, the latter infinity is not a perfection, but an infinite receptivity without determination, e.g., our intellects have an infinite openness to receive the forms of things (yet, this is not actual).
