Our “I” isn’t disposed of per se. We become more of ourselves, more human, more “I” when we become more united to God. Our “I” in effect becomes God, because we are fully incorporated into the Body of Christ and have “the mind of Christ” (per Paul).
I don’t know if that’s correct. Certainly those who receive the gift of eternal life will be divinized and become one with Christ, but we won’t become the essence of God.
“St. Paul saith, “When that which is perfect is come, then that which is in part shall be done
away.”6 Now mark what is “that which is perfect,” and “that which is in part.”
“That which is perfect” is a Being, who hath comprehended and included all things in
Himself and His own Substance, and without whom, and beside whom, there is no true
Substance, and in whom all things have their Substance. For He is the Substance of all things,
and is in Himself unchangeable and immoveable, and changeth and moveth all things else.
But “that which is in part,” or the Imperfect, is that which hath its source in, or springeth
from the Perfect; just as a brightness or a visible appearance floweth out from the sun or a
candle, and appeareth to be somewhat, this or that. And it is called a creature; and of all
these “things which are in part,” none is the Perfect. So also the Perfect is none of the things
which are in part. The things which are in part can be apprehended, known, and expressed;
but the Perfect cannot be apprehended, known, or expressed by any creature as creature.
Therefore we do not give a name to the Perfect, for it is none of these. The creature as
creature cannot know nor apprehend it, name nor conceive it.
“Now when that which is Perfect is come, then that which is in part shall be done away.”
But when doth it come? I say, when as much as may be, it is known, felt and tasted of the
soul. For the lack lieth altogether in us, and not in it. In like manner the sun lighteth the
whole world, and is as near to one as another, yet a blind man seeth it not; but the fault
thereof lieth in the blind man, not in the sun. And like as the sun may not hide its brightness,
but must give light unto the earth (for heaven indeed draweth its light and heat from another
fountain), so also God, who is the highest Good, willeth not to hide Himself from any,
wheresoever He findeth a devout soul, that is thoroughly purified from all creatures. For in
what measure we put off the creature, in the same measure are we able to put on the Creator;
neither more nor less. For if mine eye is to see anything, it must be single, or else be purified
from all other things; and where heat and light enter in, cold and darkness must needs depart;
it cannot be otherwise.
But one might say, “Now since the Perfect cannot be known nor apprehended of any
creature, but the soul is a creature, how can it be known by the soul?” Answer: This is why
we say, “by the soul as a creature.” We mean it is impossible to the creature in virtue of its
creature-nature and qualities, that by which it saith “I” and “myself.” For in whatsoever
creature the Perfect shall be known, therein creature-nature, qualities, the I, the Self and the
like, must all be lost and done away. This is the meaning of that saying of St. Paul: “When
that which is perfect is come” (that is, when it is known), “then that which is in part” (to…”

This seems to affirm what every other religious mysticism teaches.
