The Catholic Church does not teach that we are to become gods. Where on earth did you get that falsehood?
We constantly strive for holiness in imitation of Jesus Christ, but doesn’t every Christian do that?
From the Catechism of the Catholic Church which teaches that.
CCC 460 The Word became flesh to make us "partakers of the divine nature": "For this is why the Word became man, and the Son of God became the Son of man: so that man, by entering into communion with the Word and thus receiving divine sonship, might become a son of God." "For the Son of God became man so that we might become God." "The only-begotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods."
And from the teaching of those the Catholic Church holds as their “church fathers”.
Saint Irenaeus
- “Do we cast blame on him [God] because we were not made gods at our beginning, but first we were made men, then, in the end, gods?’ (Against Heresies 4, 38)
Clement of Alexandria
- “Yea, I say, the Word of God became a man so that you might learn from a man how to become a god.” Clement of Alexandria, Exhortation to the Greeks, 1.
Athanasius, bishop of Alexandria
- “The Word was made flesh in order that we might be enabled to be made gods. . . . Just as the Lord, putting on the body, became a man, so also we men are both deified through his flesh, and henceforth inherit everlasting life.” Athanasius, Against the Arians, 1.39, 3.39.
Hippolytus:
"He (man) is made God by water and the Holy Spirit after the regeneration of the laver."[ Discourse on the Holy Theophany, 8]
"Thy body shall be immortal and incorruptible as well as thy soul. For thou hast become God."[ Philosophoumena, X.34, quoted in Craig White (compiler), "Early Doctrines of the Eastern Churches".]
