God's Immutability
divine impassibility--changeable emotions in God
This is first and foremost God's freedom from external influence on his intrinsic nature and his will. Emotions do not act upon God to make him violate his existence or essence. However, the true and living God is a genuinely emotional being whose emotions are uncorruptible and always express his unchangeable existence and essence.
God's relational mutability
God is involved in pursuing, establishing, developing, and restoring relationships with those that he has made. These changing relationships expressed in time, with varying emotional responses on God's part, reveal the changelessness of God's intrinsic nature and free word.
ontological immutability
God is unchangeable in the supreme excellence of his intrinsic nature--the changelessness of God's eternal and self-sufficient being including God's existence and his essence.
ethical immutability
God is unchanging in his unconditional promises and moral obligations to which he has freely pledged himself. God is true to his word and unfailing in accomplishing what he has promised. This is a second order type of changelessness because it depends upon God's ontological immutability and the free commitment of God to choose to live in relationship with his created moral agents in his freely self-imposed and self-determined ways. God's ethical immutability is an expression within time of God's external intrinsic nature.
immutability of God in process theism
A reality of some sort must exist outside of God for God to exist. God's existence is immutable as is his ability to take in the totality of the experience of the universe, but the actual make up of God's nature is dependent upon the input of others entities into the God's nature
God as a living, active, and relational God
God constantly changes in his affairs with people as he encounters new happenings and responds to changing situations, but God's changes always express rather than deny God's unchangeable ethical nature rooted in his unchangeable existence and essence.
The Immutability of God
This is the principle that God does not change. He is the same today as He was a thousand years ago. God's nature does not change, nor does His character or attributes. When something changes, it is made better, worse, or different. But because God is perfect, He cannot be made better or develop into a holier being. There is no need for Him to change.
