We do not know whether Paul had a horse, a donkey, a camel, or was on foot. An assumption given his support by the High Priest that he did not walk is reasonable but that is all.

In Galatians 1:16 Paul writes that God "was pleased to reveal his son to me." In 1 Corinthians 15:8, as he lists in order the disciples Jesus appeared to after his resurrection,"last of all, as to one untimely born, He appeared to me also."

The Last Supper narrative describes a sacrifice, and the apostles to be priests. The Greek word used for the command “do” - “poiein” conjugated “poiete” can be rendered literally as “offer this”.  Exodus 29:38 reads: “Now this is what you shall offer upon the altar: two lambs a year old day by day continually.” The Greek word for “offer” in the Septuagint is “poiein” conjugated “poieseis”. The same usage is in Leviticus 9:7 and Psalm 66:15.

And when the Church arose from the catacombs, it was with a sacrificial priesthood.
