The heretics (who are full of demonic pride and egotism) oppose the Orthodox theology by claiming that we humans are not supposed to change.
You probably know that heresy originates in pride and egotism. All heretic leaders were extremely proud people. According to them, it is God Who must change, not man! They have based their whole theology on this perverted thesis, although the opposite is true. God is unalterable, He never changes. Moreover, according to Orthodox theology, God is ever-same (ἀίδιος, aídios), meaning He is always the same (was before all times, is and will be for ever). God is perfect, All-perfect, above all perfection. That’s why He does not need to progress, to become better or to change.
Alas! If God was ever to change, it would mean He has passions! But, of course not… God is dispassionate (ἀπαθής). He is unalterable. However, according to heretic (papist, protestant etc.) theology, God changes, indeed!
Now, please, notice how this theology unfortunately pervaded our orthodox theology. Fr. John Romanides says: “For them, in the West, Papists and Protestants, man does not change. For them, the only thing man does is that he becomes a ‘good’ boy”, meaning we only change our outward behavior.
Our inner part, our essence, our soul (essentially) does not change. We only become externally a ‘good’ boy. And when we, from ‘bad’ boys and girls, become ‘good’ boys and girls, God loves us or, else, He turns away from us. What a strange theology! Totally wrong!
This means that, according to them, God can hate and abhor! If we continue being ‘bad’ boys and girls, God does not love us. Can you please tell me, have you realized that this kind of perception of God has also pervaded our orthodox way of thinking?
This is a result of the influence of western standards on orthodox catechism. The same teachings are often to be observed in contemporary orthodox Sunday-Schools: “If we become ‘good’ boys and girls, God changes and becomes also ‘good’!” Do you realize where we end up being with all this absurd theology?
And, from a past situation, when God supposedly did not love us, He now ends up loving us. “When we become ‘bad’ boys and girls, God is angry, and when we become ‘good’, God is happy”!
Unfortunately, these are the opinions prevailing in Europe. This is the theology of the West. In fact, this teaching is a total disproof of God Himself, because God is not like this at all. This is the reason why the West has ended up actually refusing God and getting into a state of pure atheism (a good Greek source on the theology of the death of God can be found here).
