***FK, in general this sounds very Orthodox.***
What's your take on this, from the Westmister Confession of Faith.
Chapter XIII
Of Sanctification
I. They, who are once effectually called, and regenerated, having a new heart, and a new spirit created in them, are further sanctified, really and personally, through the virtue of Christ's death and resurrection, by His Word and Spirit dwelling in them: the dominion of the whole body of sin is destroyed, and the several lusts thereof are more and more weakened and mortified; and they more and more quickened and strengthened in all saving graces, to the practice of true holiness, without which no man shall see the Lord.
II. This sanctification is throughout, in the whole man; yet imperfect in this life, there abiding still some remnants of corruption in every part; whence arises a continual and irreconcilable war, the flesh lusting against the Spirit, and the Spirit against the flesh.
III. In which war, although the remaining corruption, for a time, may much prevail;[10] yet, through the continual supply of strength from the sanctifying Spirit of Christ, the regenerate part does overcome;[11] and so, the saints grow in grace,[12] perfecting holiness in the fear of God.[13]
I'm not exactly sure what this means:
"They, who are once effectually called, and regenerated,...."
That said, compare the Westminster Confession with these:
"Can a man take fire into his bosom, and his clothes not be burned?' (Prov. 6:27) says the wise Solomon. And I say: can he, who has in his heart the Divine fire of the Holy Spirit burning naked, not be set on fire, not shine and glitter and not take on the radiance of the Deity in the degree of his purification and penetration by fire? For penetration by fire follows upon purification of the heart, and again purification of the heart follows upon penetration by fire, that is, inasmuch as the heart is purified, so it receives Divine grace, and again inasmuch as it receives grace, so it is purified. When this is completed (that is, purification of heart and acquisition of grace have attained their fullness and perfection), through grace a man becomes wholly a god." +Symeon the New Theologian
And these from +Gregory of Sinai:
"A person is perfect in this life when as a pledge of what is to come he receives the grace to assimilate himself to the various stages of Christ's life. In the life to come perfection is made manifest through the power of deification."
"He will share in Christ's glory who, through being formed in Christ, has received renewal by the Spirit and has preserved it, and so has attained to ineffable deification. No one, there, will be one with Christ or be a member of Christ, if he has not become even here a receiver of grace and has not, thereby, become 'transformed by the renewal of' his 'mind'"
And this by +Gregory Palamas:
"Moses and David, and whoever else became vessels of divine energy by laying aside the properties of their fallen nature, were inspired by the power of God... They became living icons of Christ, being the same as He is, by grace rather than by assimilation."
Looks pretty much the same if we understand the words the same way.
