" You had mentioned that the Mennonite/Amish might know this?"
Me? I'm sure if I did I was kidding!
I must say it is astonishing to me that that as recently as the 19th century Anglican hierarchs understood and preached Theosis. Think for a moment on what effect that belief, regularly preached and believed, might have on a church!
With the growing interest in Eastern Orthodox/Evangelical rapprochement, it is essential that theosis studies be pursued. Evangelicals may receive considerable benefit from a clear understanding and judicious appropriation of the doctrine. This is so particularly in light of the crying need for a robust, biblical theology of the Christian life that will refute and replace the plethora of false spiritualities plaguing Church and society.And elsewhere
A more Westernized definition comes from Philip Edgecumbe Hughes, the deceased evangelical Anglican clergyman, biblical scholar and theologian in the Reformed tradition. Like a fair number of older Anglicans, he understood and saw considerable value in the doctrine of theosis.
I need to go away and get some work done, but will be back in a couple of hours.
