Ultimately, as we get more Trinitarian and 'eternal' in our theology..
we should be mapping every aspect of Christian life and mechanics to the unchanging dynamics and character of the Father, Son and Holy Spirit as they have always interacted with each Other
But yet not everything is the same....
there is one other element to add in that is different from what has been happening in eternity
The Cross (meaning from incarnation to ascension)
The Cross is necessary because when God created - creation was outside Himself, as in creation is separate from Him
And so He goes into creation to bring it back to Him
We can summarise all of creation into 1 being - Adam
Adam (the fullness of created things) is apart from the Other Being - Christ (in which is the fullness of Deity)
Adam first must break, then Christ comes into Adam, then Christ must break, then Adam comes into Christ
now then we are back to eternal Trinitarian dynamics - church incorporated
what ever is 'left over' is thrown away... a strange new dynamic of eternal sinfulness
