The homily seemed to say that the vineyard was the Word of God, which evil men of all ages wish to make their own to serve their own selfish interests. Yet in so doing, they "kill" the power of God. Christians do this when they are "not open to the newness of the Word of God," and "are not obedient to the Word of God."
The Pope stressed humility and prayer to achieve docility to the Word of God, and warned them to "not cage the Holy Spirit."
The Bear's Interpretation
The parable of the wicked husbandmen has always been interpreted two ways.
The "literal" interpretation is a recapitulation of Jewish history, as Israel is frequently described as a vineyard in the Old Testament. The agents the owner sends are the prophets, who were often treated shamefully. The son is, of course Jesus, and herein Christ predicts (and provokes) his passion. The owner -- God -- takes away the vineyard from the Jews and gives it to another people, that is, the Gentiles.
The moral (or "tropological") sense is that we must respond to God's repeated offers of grace, or we will be no better than the wicked husbandmen, and will be condemned by our Judge.
Pope Francis' emphasis, however, is on the motive for the violence of the wicked husbandmen. They want to possess the vineyard as their own. We must not use the Word of God as a tool to promote our own selfish interests, to "steal" it. We must conform ourselves to the Gospel. Catholics have always been taught this. Certainly, by speaking of ideologies and theologies the Pope cannot be hinting at any uncoupling of the Word of God from the Church's teachings contained in her historical consensus nor a criticism of Catholics who follow them.
Who uses Holy Scripture outside of the Church's unique authority to interpret them, and seeks to "possess" them according to their private interpretations and theologies? The only possible answer is those who have separated themselves from the Church: both formally, as have Protestants, and practically, such as those who wish to change the Church's teachings.
So what do you think? Is the Bear properly understanding the Pope's homily or not? He would love to hear your opinion.
