The New Testament doesn’t mention any of these Christian feasts, and some Christians think it’s wrong for the church to observe any feast besides the weekly Lord’s Day. Since it’s not commanded, it’s forbidden. But we aren’t children any more. Our calendar isn’t controlled by the sun, moon, and stars. We don’t need direct revelation from God to schedule times with the Bridegroom. We’re in heavenly places with Jesus as time lords. The church’s leaders, like Mordecai, have authority to establish feasts and commemorations in keeping with the model of Israel’s calendar, which is laid out so carefully in the Bible.
