God does.
By whom he hath given us most great and precious promises: that by these you may be made partakers of the divine nature: flying the corruption of that concupiscence which is in the world (2 Peter 1:4).
But thanks for posting the CCC that shows that the Catholic Church adheres to Scripture.
Protestants abuse God's privilege and assume for themselves the power that rightfully belongs to God to declare what is true, right and just.
Once again the Catholic Church twists the meaning of scripture. The Greek word used is koinónos which means a sharer, partner, or a companion. I can share or partner with someone but that doesn't make me that person. Neither by becoming sharers or companions with God do we become divine or a god. The Catholics and the Mormons need to get together and figure that out.
