A petrified orthodoxy has lost its scriptural spirituality and thus also its credibility and its efficacy. It is embalmed piety. Fundamentalism with its rigidity, censoriousness and self-righteousness is more than a faint recollection. A mere retrogression glorifying the remote past denies the ongoing guidance of the Holy Spirit. The willingness to move toward a truly reformed progressiveness is often buried by the reluctance to face openly the non-theological obstacles causing disunity.
Prayers naturally have their place in ecumenical activities.
But the searching question is whether it is the chief part. Prayer also includes intercession. The broadness, comprehensiveness and the intensity of intercession are indicative of the attitude toward and zeal for the kingdom of God. There are small Reformed churches in Croatia and Serbia struggling to survive, even against the Serbian-Orthodox Church that leaves the impression of being more aggressive than Milosevic. There are Christians in former communist countries and fundamentalistic Islam countries that face continuing persecution.
