Chapters 25–27 of Isaiah contain certain elements found in later apocalyptic literature: worldwide judgment, cosmic upheaval, God’s defeat of dark powers and deliverance from them, and the enthronement of God in the temple on the holy mountain in Jerusalem. The image of a banquet, which God hosts on this mountain, conveys the abundance and joy that the rescued faithful will experience once God has defeated the dark forces. The most powerful of these, death itself, will also fall, leaving nothing to mar the joy of God’s reign over “all nations” as the devastated world is renewed. Those who have been brought to God’s mountain will be safe from all harm, for the divine protection (“hand”) will rest on the mountain.
Paul has apparently received some money from the Philippians, prompting him to comment on the vicissitudes of his apostleship, which has its material as well as spiritual high and low points. At times he has been comfortable and at other times his circumstances have been more “humble.” From this he has learned how to “go with the flow,” accepting whatever comes along. As always, the strength to persevere comes from Christ, who supplies everything Paul could possibly need. This confidence in the providential care of God allows Paul to be open to whatever comes. Throughout the letter, in various ways, this theme of radical selflessness has appeared, rooted not only in the example of Christ but also trust in God.
Jesus teaches consistently in Matthew’s Gospel that while absolutely everyone is invited to enter the kingdom of heaven, the price of admission is high. The gate is narrow and the road is difficult, and few find it (7:13–14). The guest in the parable represents those who have failed to understand this fundamental teaching. He has taken up the king’s generous invitation, but by failing to dress appropriately (even though, we must assume, he could have), he has demonstrated an overly casual attitude, treating the event as if it were simply a matter of “come as you are,” an insult to the generosity of the king. The kingdom of God, the parable reminds us, is not something we should take for granted.
