"This will be the case when every love, every desire, every effort, every undertaking, every thought of ours, everything that we live, that we speak, that we breathe, will be God, and when that unity which the Father now has with the Son and which the Son has with the Father will be carried over into our understanding and our mind, so that, just as he loves us with a sincere and pure and indissoluble love, we too may be joined to him with a perpetual and inseparable love and so united with him that whatever we breathe, whatever we understand, whatever we speak, may be God. In him we shall attain, I say, to that end of which we spoke before, which the Lord longed to be fulfilled in us when he prayed: ‘That all may be one as we are one, I in them and you in me, that they themselves may also be made perfect in unity.’ (John 17:22-23)"
