Theosis is not a belief that is commonly held in Protestantism.... It tends to be an EO doctrine clouding the Creator/creature distinction.....Mormons look to become gods ......
We look to sanctification ... the process of growing more Christ like...one more time..Christ in you the hope of Glory ..
For me the purpose of life is not to become god.. but to glorify God and then to enjoy Him forever
Not sure what you mean by this. Christ doesn't become "part" of my body, I become part of His body.
You needn't go beyond what Paul says (repeatedly,and quite evocatively) about us being members of His body (which is, precisely, incorporation) as well as what Peter says about us participating in the divine nature.
This isn't what the Mormons are talking about. They are not, as I understand it, monotheists; they believe in as many gods as there are inhabited planets. (I don't want to misconstrue them, take with a grain of salt, I am no expert on Mormon doctrine.) But as I understand it, they become 'gods.' They do not participate in the divine nature of the One God, which is a union through love, not by a multiplication of 'gods'.
Sorry, I have to duck out now. I'm still in the midst of a big writing project.
