I always thought Pentecost was a one-time thing. Like the Resurrection. But the way the first reading (Acts) starts, it’s like an every year thing.
Like Andrew had texted everybody. “Peter and I are doing Pentecost at his place. John’s bringing his famous hummus. See you Sunday.”
And that's kind of it. Because Pentecost was already a thing. “Pentecost” is Greek for Shavuot. In Jesus’ time, Shavuot was one of the traveling festivals. Where everyone went to Jerusalem.
Which is why they were all together. For Pentecost. But the Pentecost they got? Not the Pentecost they were expecting.
More on this tomorrow. Readings for Pentecost
