Over at Unam Sanctam, Boniface faces up to the difficulties that now confront the bishops in Rome. Will God let the true church go? He says, of course not and invokes the parable of Isaiah 5:1-7:
This is what God means when He says that He gave the vineyard over to grazing. A landowner cannot ever “destroy” his property, in the sense that land as such is indestructible – but he can certainly alter its use, sometimes in radical ways. When the vines did not yield grapes, God plucked them up, had the walls trampled down, and gave the vineyard over to the wild animals (the nations) for grazing. And because of the reckless, presumptuous overconfidence of the Israelites – whom the prophet Jeremiah says were led astray by false prophets who only spoke what the people wanted to hear – they were caught unaware and led to destruction.
My friends, just because God has promised that this vineyard – the Church – will always endure and that He will always look after it does not mean that the situation of the Church in this world could not be radically altered. In the case of the vineyard, God is still “maintaining” the land when He breaks down the wall and gives it over to grazing. He is maintaining the way any husbandman does: by putting the land to its highest and best use. If the vineyard consistently refuses to bear fruit for the Master, there is no reason to think He will not break down our walls and give us over to grazing. This has already happened to a large extent over the past fifty years.
Boniface concludes that God will not abandon his church:
Will God ever abandon this little piece of property which He has claimed for Himself and bought with His blood? Of course not. Such a thing cannot be. Could He choose to give it over to grazing? Could He break down its walls? – that is, many of the visible structures that have provided security in the past? Could He command His clouds not to rain on it? – that is, withhold many of the gifts that He had showered upon the Church in ages past? Could He pluck up much of the vines by the roots and cast them away to be burned, and could He give over the land to the grazing of animals, who will trample it down with their hooves, grind the vegetation between their teeth and foul the earth with their dung? Of course He could do all this. In fact, unless we bear fruits befitting repentance, He will most certainly do all things.
Perhaps then – and only then – will our little, beloved piece of ground be disposed to again produce good fruit. But until then, let it be given over to grazing.
Is that what happened to Israel or Judah? Is this not an ominous precedent? God did make promises to Abraham but then sent Abraham’s descendants into exile. Was that an example of the gates of hell prevailing against the OT church? Or was it part of a plan to bring all the nations into a spiritual Israel, the church? So if you think of Israel as a type, the Mosaic Covenant as a kind of republication of the Covenant of Works, and of the Israelites as a kind of second Adam (who makes obvious the need for the final Adam), you might also view the Holy See as a type, Protestantism being a better rendering God of the church’s place in redemptive history. But if you think of Israel as the substance and you’re drawing parallels with the church, you might need a few nips to get to sleep at night.
