Luther's lost teachings: 'Christ Present in Faith'

Has anyone read "Christ Present in Faith: Luther's View of Justification" by Tuomo Mannermass and Kirsi Irmeli Stierna?

They are Lutheran theologians from Finland who are working to get back to Luther's original -- and it would appear mystical view -- that Christ enters the believer through faith.

Here are a couple quotes from the book that capsulize the theology:

"...according to the Reformer [Luther], the union between the believer and Christ is so complete that these two become 'one person.'

"'Christ,' he [Luther] says, 'is fixed and cemented to me and abides in me. The life that I now live, He lives in me. Indeed, Christ Himself is the life that I now live. In this way, therefore, Christ and I are one.'

"Christ is freedom, righteousness, and life, and by his presence he drives sin, death, and curse away from the believer, making these 'disappear.'"

"God is seen in this view as an incessant movement toward transcendence -- that is, toward God, who nevertheless remains in 'heaven.' According to Luther, however, the true faith unites the Christian with God who in God's agape-love has 'descended' to us and who is present in the sinner by being present in faith in all God's fullness. Faith is 'heaven.'"

Finally, and this is pretty much the summation and conclusion of the book, the authors argue: "Luther does not hesitate to conclude that in faith the human being becomes 'God,' not in substance but through participation. This notion, which has been forgotten in Protestant theology, is an integral part of Luther's theology of faith, if interpreted correctly.”
