piety101:
Mary is not divine and neither are the saints in heaven. When Peter spoke of us partaking of the divine nature, he was referring to his Holy Spirit or the spirit OF God, when we are baptized. God is not reproducing “little gods” in heaven. Someone has misguided you with shades of Mormonism.

St. John of the Cross, Doctor of the Church, would be amused to see himself accused of crypto-Mormonism:
“. . .the Bridegroom [Christ] communicates Himself to the soul by means of the adornment of these virtues, He feeds on the soul, transforming her into Himself, now that she is prepared and seasoned with the flowers of virtues, gifts, and perfections, the seasonings with which, and among which, He feeds on her. By means of the Holy Spirit, who prepares the dwelling, these virtues delight the Son of God so that through them He may feed more on the love of the soul. This is the characteristic of the Bridegroom: to unite Himself with the soul amid the fragrance of these flowers.” The Spiritual Canticle, Stanza 17, #10.
"Turn Your face toward the mountains. . .The face of God is the divinity, and the mountains are the soul’s faculties (memory, intellect, and will). This verse is like saying: Let Your divinity shine on my intellect by giving it divine knowledge, and on my will by imparting to it divine love, and on my memory with the divine possession of glory.
“The soul asks in this line for everything she possibly can ask of Him. She is no longer satisfied with the knowledge and communication of the “back” of God - which was His communication to Moses [Ex. 33:23] - and which is knowledge of Him in His effects and works; she can only be satisfied with God’s face, which is an essential communication of the divinity of the soul. This communication is not brought about through any means, but through a certain contact of the soul with the divinity. This contact is something foreign to everything sensory and accidental, since it is a touch of naked substances - of the soul and the divinity.” Ibid. Stanza 19, #4
“. . .Beloved, first turn to the interior of my soul, and be enamored of the company - the riches - You have placed there, so that loving the soul through them You may dwell and hide in her. For, indeed, even though they are Yours, since You gave them to her, they also belong to her.” Ibid. Stanza 19, #6.

1726 The Beatitudes teach us the final end to which God calls us: the Kingdom, the vision of God, participation in the divine nature, eternal life, filiation, rest in God.
1812 The human virtues are rooted in the theological virtues, which adapt man’s faculties for participation in the divine nature: for the theological virtues relate directly to God. They dispose Christians to live in a relationship with the Holy Trinity. They have the One and Triune God for their origin, motive, and object.
1988 Through the power of the Holy Spirit we take part in Christ’s Passion by dying to sin, and in his Resurrection by being born to a new life; we are members of his Body which is the Church, branches grafted onto the vine which is himself: [God] gave himself to us through his Spirit. By the participation of the Spirit, we become communicants in the divine nature. . . . For this reason, those in whom the Spirit dwells are divinized.
