Let me say a few words about each reading. Collosai, a town Paul had never visited, was a crossroads in the center of what we now call Turkey. The leading Christians there had written to Paul about a troubling problem.
The Christians there had to put up with followers of a strange branch of Astrology that taught that each of the planets was being governed by separate brand of angel. They had such names as Principalities and Powers. Paul in this letter, instead of arguing against the existence of such angels, chose to present Jesus as more glorious and powerful than any angels could be.
The Gospel presents the brothers Simon and Andrew as the fishing partners of
James and John. It seemed that they manned long seining nets together.
