"Scripture and Tradition never cease to teach and celebrate this fundamental truth: ‘The world was made for the glory of God.’ St. Bonaventure explains that God created all thigns ‘not to increase his glory, but to show it forth and to communicate it’, for God has no other reason for creating than his love and goodness: ‘Creatures came into existence when the key of love opened his hand.’ The First Vatican Council explains:
This one, true God, of his own goodness and ‘almighty power’, not for increasing his own beatitude, nor for attaining his perfection, but in order to manifest this perfection through the benefits which he bestows on creatures, with absolute freedom of counsel ‘and from the beginning of time, made out of nothing both orders of creatures, the spiritual and the corporeal…’
The glory of God consists in the realization of this manifestation and communication of his goodness, for which the world was created. God made us 'to be his sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, for ‘the glory of God is man fully alive; moreover man’s life is the vision of God: if God’s revelation through creation has already obtained life for all the beings that dwell on earth, how much more will the Word’s manifestation of the Father obtain life for those who see God.’ The ultimate purpose of creation is that God 'who is the creator of all things may at last become ‘all in all’, thus simultaneously assuring his own glory and our beatitude.
We believe that God created the world according to his wisdom. It is not the product of any necessity whatever, nor of blind fate or chance. We believe that it proceeds from God’s free will; he wanted to make his creatures share in his being, wisdom, and goodness: ‘For you created all things, and by your will they existed and were created.’ Therefore the Psalmist exclaims: ‘O Lord, how manifold are your works! In wisdom you have made them all’; and ‘The Lord is good to all, and his compassion is over all that he has made.’" (CCC 293 - 295)
“God created the world to show forth and communicate his glory. That his creatures should share in his truth, goodness, and beauty – this is the glory for which God created them.” (CCC 319)
"God created everything for man, but man in turn was created to serve and love God and to offer all creation back to him:
What is it that is about to be created, that enjoys such honor? It is man – that great and wonderful living creature, more precious in the eyes of God than all other creatures! For him the heavens and the earth, the sea and all the rest of creation exist. God attached so much importance to his salvation that he did not spare his own Son for the sake of man. Nor does he ever cease to work, trying every possible means, until he has raised man up to himself and made him sit at his right hand." (CCC 358)
Nowhere in the Catechism does it state in any way that God created the universe or mankind for the Blessed Virgin Mary. And as for the love of Mary, again, it is to be distinct from the love that is due to God alone. Yes, Mary is to be venerated. Venerated even above all the other saints and angels, and you are correct that the Church’s term for this veneration is Hyper-dulia. But this is not the same as the love due only to God. Nor is Mary perfect as God is perfect. She is the perfect creature. Key word: creature. God is not a creature, He is the Creator, and is infinitely more perfect than anything He has made.
