Then Peter said to Jesus, "Lord, it is good for us to be here; if you wish, I will make three dwellings here, one for you, one for Moses, and one for Elijah." (Matthew 17:4)
I heard this passage as part of yesterday's gospel reading. The version we read continued on by stating that Peter didn't know what he was saying.
The cloud came next, out of which the Father spoke, instructing us to listen to His son. Then the cloud lifted, and Moses and Elijah were gone. Only Jesus remained.
Peter wanted to build dwellings, or as other translations call them booths, or even tabernacles. Three of them. One for the law, one for the prophets, and one for this newcomer, this Jesus.
Three monuments to three institutions.
But he didn't know what he was saying. There was to be only one.
One perpetual tabernacle.
