maybe I’m not attaching the proper concepts to the words ‘perfect’ amd 'complete. I envision heaven as an eternal movement towards absolute happiness, or happiness not as a possession but like God. God is happiness. I was conceptualizing that as complete happiness. That in heaven happiness would be eternally more united to God. Eternally becoming more divine in meaning.
I think it’s a question of semantics. The terms are often used as synonyms interchangably.
However, the word “complete” regarding happiness denotes a state of perfect contentment of being already there. The term “perfect” really does the same. God is perfect and complete.
I just used the word “complete” (or completion)
for happiness on the natural plane and “perfection” on the spiritual plane in an earlier post. It seems that a person (or animal?) can feel perfectly contented, that is complete. But to acquire a state of perfection (as St. Teresa of Avila and other saints define), it is necessary to travel the spiritual highway conquering vices and gaining virtue so as to become perfect in that we are united to God.
