Yes, God created the Universe to share His own happiness with other rational creatures, such as Angels and mankind.
God did not have to create anything but the fact that He did shows that He wants to share His happiness with others who would not exist if it were not for him.
Affection is not a corollary of love. How many marriages do you know of where there is love, yet the individuals have no affection for each other?
Of course it is.
You cannot love something without being affectionate to it.
If you do not have affection towards it, you do not love it.
Example: the cops go to a domestic disturbance where the man is beating the tar out of his woman. The cops pull him and and start to stuff him in the paddy wagon. The woman takes a frying pan to the back of the cops’ heads. Affection? No. Love? Sure.
The wife still may love the husband, but the husband does not love the wife.
No man who hits his wife loves his wife and his wife is deceived if she thinks that he does.
“God created the Universe to share His own happiness with other rational creatures, such as Angels and mankind.”
I don’t think that I’d say that angels and mankind are rational on the order of God. If you said that God created mankind in order to populate His universe, I’d agree with you. There are a few things that He’d have us do, such as worship and love Him.
