What it means to empty ourselves?

To be assumed by the Person of Christ, to act in his name, first of all, we have to empty ourselves. Second, we must be lifted up ourselves. In the second chapter of the letter to the Philippians, St. Paul says of Christ that the divine nature was his from the first. He did not need to snatch at equality with God, because he was God. He made himself a nothing, assuming the nature of a slave. He made himself a zero. He emptied himself. There was a human nature, but no human person in Christ. There was only the divine Person. That means that in a certain sense we no longer have a human person. Believe me, our spirituality has been ruined by the so-called philosophy of identity. I've got to be me. I've got to do my thing. Since when? Doesn't charity mean doing the other person's thing? Why this affirmation of the ego? Why do we have to act in a certain way to attract the attention of others to our human personality? There's no human personality in us. Christ is in us at all times, acting through us, using us as his instrument.
