Sharing in the divine nature is something that is possible only for the Three Hypostases of the Holy Trinity.
I understand your POV and respect you and Orthodox position.,but I will stay within the teaching of the west.
IMHO,since God uses His creature to build up the Church through the ages ,it seems to me that this would have to include the triune nature of God guiding that process through human nature.
That said,I will refrain from arguing an over 1000 year old problem between us and Pray for complete unity for the leaders of both sides to figure out.
I am certainly not qualified to handle this topic. All I can do is to pray and have love and respect for my Orthodox brothers and sisters whom we are most importantly united in the Eucharist
I wish you a Blessed day!
