A sermon I listened to pointed out that in Matthew 16:19, Jesus used the same terms to characterize Peter's authority that Isaiah used in Is 22:22 to describe Elikiam's authority as head of Hezekiah's household. This is used in replacing Shebna. I have only encountered cross references that go one way from Isaiah to Matthew, not Matthew to Isaiah. It is significant to me because the pastor goes on to suggest that this is a verse that grants the church and or Pope the right to 'loose/bind' people on earth as in heaven. This is predicated on the possible notion that the apostle Peter was the first Pope, and that authority was delegated to each successive Pope. This is a mainly Catholic assertion but I have seen other denominations make this claim. I am not looking for a denominational analysis. 1. How can I access cross references of Matthew to Isaiah? 2. I have read commentaries and have not found any mention of this terminology and characterization. How would the Logos' pros use Logos to determine if Elikiam's authority relates to Peter's authority? 3. Is there a good book that answers my question on this study? This is not really a rabbit trail but I am trying to find the biblical truth of the matter.
