Excerpts from Beyond Calvin: Essays on the Diversity of the Reformed Tradition (underlining mine):
"Bucer is one of the central figures in the oft-rehearsed debate amongst Protestants about the true marks of the church [....]The debate happened around a proposed third mark of the church: the practice of church discipline."
"This synthesis of Erasmian humanism and Lutheran soteriology would become a hallmark of the Strasbourg reformer’s thought."
"This reputation for tolerance, or to use Erasmus’s term, harmony, is, in fact, part of what drew Bucer himself to the city [of Strasbourg]."
"Bucer would strongly defend this understanding of the church. In the letter he wrote, 'We are often too lenient towards those who agree with us and accept our teaching and too severe toward those who dissent and do not yet accept our teaching.'"
Such was the severity of Zwingli and Luther. Zwingli drowning those who disagreed, and Luther gave his nefarious nod to Fritz Erbe being lowered down into a "terror hole" till he recanted of his errors. But in what sense (e.g., directly or indirectly) did Luther and Zwingli give their respective nods to religious violence? One scholar writes:
“Luther did not resort to violence against [heretics] directly. By 1525 he had driven Karlstadt[and] Munzer…out of Wittenberg and he had refrained from calling for their deaths. Yet when it came to rebellion rather than heresy, Luther was willing to contemplate violence…and to call for the slaughter of the peasant rebels whom he compared to rabid dogs. Zwingli took a harsher approach. By 1525, under his leadership, the city of Zurich was aggressively harassing those who refused to accept infant baptism. And in 1527, when adult re-baptism was declared a capital crime, the execution of anabaptist heretics became routine. The first of these martyrs, Felix [Munz or Munst?–CD] was drowned in Lake Zurich — a fitting punishment, according to the Zwinglians, for someone who abused the waters of baptism…ironically, but logically, martyrdom confirmed for them their identity as the true Church of Christ…a most painful self-fulfilling prophecy" (Carlos M. N. Eire, Reformations: The Early Modern World, 1450-1650; my transcription of this work as an audiobook).
"Bucer was ready to admit that this broad definition included Catholics: 'there are many who belong much more to Christ among those who are considered papists than among those who seem to be evangelical.'"
Bucer's "broad definition" of essential gospel doctrine being the following:
‘Christ is the unique savior of mankind, true God, true man, from whom we await all things.’
Thus, Bucer did not know or believe the true gospel of Christ who is actually a Just God and a Savior; not the "try-and-fail savior" of Roman Catholics and moderate and "'well-meant' offer" Calvinists.
"The centerpiece of Bucer’s approach is patient, irenic discussion done with the goal of preserving Christendom by helping more nominal or confused Christians take up the yoke of Christian discipline. Understanding this point helps to explain Bucer’s approach to Marpeck."
I don't know who Marpeck is (presumably an Anabaptist), but one wonders who the "confused Christians" are. How about Nestorians or Arians? Or is that "too irenic," even for Bucer?
[The God-hating Roman Catholics hold to an "orthodox shell" of the Trinity and the Incarnation and Deity of Jesus Christ, but when the Hammer of God's Word cracks open this husk, the damnable kernel inside is revealed. The "damnable kernel" includes such doctrines as Universal Atonement, Purgatory, the Mass, etc.]
"Bucer sees church discipline and unity as being closely related—the goal of discipline is love. When the body is splintered such that discipline cannot be practiced coherently within the church, that goal is compromised."
Would it be loving to discipline those who carved or hammered out all those years at Westminster Abbey, the facinorous fiction of "as if the offending party were dead"? Would it be an instance of splintering to discipline the framers of the Westminster Confession for strengthening the hands of adulterers with such a fanciful phrase?
"It is here, then, that we see Bucer’s sharpest departure from the later proponents of the third mark of the church. Whereas the radicals and later the Presbyterians of England would be marked by a sort of precisionist spirit that demanded full doctrinal purity before union could be assumed and joint work done, Bucer embraced a broadly irenic style of faith that sought common cause not only with radicals, but also with Roman Christians. Bucer’s ecumenism, if we can use that term, was never unprincipled or lacking in theological roots. The goal was the promotion of Christian love within local churches and Christendom more broadly. Discipline served that goal. For Bucer the work of Christian reconciliation and Christian discipline are not only not at odds, they are one and the same."
Therefore, Bucer is a principled and promiscuous whore who commits spiritual fornication with just about every passer-by, under nearly every green tree.
