The apostle Paul writes that God’s “invisible attributes, as in his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made” See Rom. 1:20 & Act. 17:26. The calendar of Israel made a connection between the nature of God and the demonstrations of his goodness in the seasons.
In the Bible, many events are recorded on the backdrop of Jewish festivals. John’s gospel describes the life of Jesus by these events commanded in Leviticus, see John. 2:23, 5:1, 6:4 & 22, 7:2 & 23, 37-39, 10:22, 13:1, 19:14 & 31, 42, 20:1. He even includes the Feast of Purim not in Leviticus but Esther. Our practice of gathering together in local communities for worship every week is rooted in the Sabbath principle of Leviticus 23:3. In Old Testament times, weekly assemblies were held on the seventh day of each week. Christians have historically viewed the resurrection of Jesus from the dead on the first day of the week as indicating a change in the day for worship to the first day of the week. This faith is based on the command of Christ, after his resurrection, for the disciples to regather to meet with him in worship on the first day of the week (Luke 24:13–49), a pattern repeated by the New Testament church (see Acts 20:7; 1 Cor. 16:2).
