I highly recommend bookmarking and following a new blog by Rev. Robert Baker, whom you may recall from his "Bioethike" blogging adventure. This new venture is called the Lutheran Marriage Initiative.
Let me briefly explain the importance of this effort by asking a question:
Considering contemporary challenges to the Christian faith, such as so-called "homosexual marriage," what do we need to do to regain and retain a strong hold on orthodox doctrine?
I would suggest that we absolutely must revive the "loci" method of teaching.
Homosexuality is a sin, yes, and Scripture is clear on this. We do not believe, as the ELCA does, that our fathers in the faith were misinterpreting Scripture for 2000 years.
But let's rewind to just a few decades ago when the culture we live in began to see contraception as acceptable in marriage, redefining marriage as being primarily about companionship and mutual pleasure, at the expense of the procreative purpose.
What was the church's response? The Scriptures our fathers in the faith unanimously interpreted for 2000 years as condemning contraception were reinterpreted, just as the verses condemning homosexuality are now.
How did this happen? We lost the broader epistemology which was employed by the great orthodox Lutheran theologians, which includes natural law and finds its best expression in the loci method rather than a myopic look at specific Bible passages that condemn specific sins.
With regard to homosexuality, we lost the locus on marriage that teaches us, among other things, that an intrinsic quality of marriage is its procreative nature. THIS is why homosexual "marriage" is not just a sinful perversion, but in truth an impossibility! It is against the created order.
We need to return to teaching properly about the positive locus of marriage - teaching about its procreative purpose and nature. Then, the negative perversions can be seen clearly in contrast to the positive locus.
May God bless this new initiative of Rev. Baker's in so doing!
