Piecing together from Tillich:

'Paradox points to the fact that in God's acting finite reason is superseded but not annihilated; it expresses this fact in terms which are not logically contradictory but which are supposed to point beyond the realm in which finite reason is applicable.'

'conquers existence under the conditions of existence...'

'breaks into our experience from above it...'

'systematic theology is a constructive task...it tries to give us an interpretation of the Christian message which is relevant to the present situation...'

'estatic reason is reason grasped by an ultimate concern. Reason is overpowered.'

'the result... not a new production but a transformation.'

Tillich writes of the 'primitive believer'.

Consider Genesis 12.1: 'In (Abra(ha)m), all the families of the earth shall bless themselves.'

Tillich advocates an 'encounter with non-Christian religions.' He criticizes the 'Reformation sects and evangelical biblicism' that 'denies that experience can become a source of systematic theology at all.'

This is all a bit serious. I like the importance of 'transformation' over 'new production'. I got bogged down in Tillich's Systematic Theology, Volume One after the introduction. Always drawn to the theme of Jesus sacrificed between two 'thieves' to a higher resolution and his 'before Abraham was, I am', Bethel (formerly Luz), return to original covenant and integrating first born, Hagar covenant, a constructive integrative reading of texts. Don't worry, I am not in the bitter Steppenwolf stage but in the pleasant.
