Do you have any insights that don’t require studying 1,000 years of history?
Let me try from memory…
First, keep in mind the parable of the mustard seed…from a small seed to a sturdy, big tree.
Liken the Church to this mustard seed.
In the west…a strong papacy emerged…to keep the west together…a necessary development-maybe or maybe not…with God’s guidance…

…think about it.
In the East…due the Islamic hegemony, the Eastern churches could not come together…could not develop as the West did. They essentially became separate national or country based churches…they did not grow into the big mustard tree like the west.
And as the Western church grew…how would the Church respond to the growth and advancement…would you say Christ has stopped guiding the Church or there is the hand of Christ behind the moves, the growth of the Church and how it responds to this.
My question is…with the declaration of doctrine of infallibility…is the Church, the world, better served by it or not? Is it needed because of how the world has grown?
Do you trust the Holy Spirit that it is still there guiding the Church?
Another insight…should there be one voice of Christ for the Church or several voices all claiming to speak for Christ here on earth?
If there is only one…would it be the Bishop of Rome? If not the Bishop of Rome…who would you say can speak as the voice of Christ here on earth?
Would you take the Bishop of Constantinople? of Antioch? the Archbishop of Canterbury? From the protestant world, and their thousands of denoms…who would you pick to be the voice of the Church?
