Yes, I see the reign of God in "becoming one flesh."  And I read your article where you speak eloquently about the effects upon children of parents who have been excluded and deprived of hope because of the indissolubility of marriage.

In your article you say that such parents who humbly approach the Eucharist should not be denied communion, but that only God can discern and provide mercy.  You reason that this preserves God's law, by which you mean the indissolubility of marriage.

I agree with your conclusion that divorced and married who humbly approach the Eucharist  should not be denied communion.  But I would not go so far as to enshrine indissolubility, comprehensively interpreted to cover those whose marriages fail for whatever reason, as God's will.  Granted, the church has taken indissolubility as God's law.  I think that is a mistake, even an idolatry.  It is better to hope for indissolubility.
