The notion of separate sacred and secular vocations was rejected by the reformers, thus introducing the possibility of doing God's work in God's presence whether that work was in the kitchen or at the altar. All places were therefore potentially a sacred backdrop for spiritual life, worship, and work. This did not mean that they gave up regular meeting for worship. The Sunday service of worship continued to serve as the anchor of spiritual life for most Protestants, during the Reformation and now. Most Protestants follow the ancient tradition of the early Church by celebrating the Sabbath on Sunday in commemoration of Jesus' resurrection, rather than on Saturday. Seventh-day Adventists and Seventh Day Baptists celebrate the Sabbath on Saturday because that is the day set aside in the Hebrew scriptures. ("Sabbath" in Hebrew means "seven," and is set aside in the Ten Commandments as a holy day because the seventh day is the day God rested in the creation story.)
The focus of Protestant worship is usually the sermon. This is because Protestants share the conviction that salvation comes through accepting the promise of God's forgiveness for sin, and that this promise—based in God's character as revealed in the redemption accomplished by Jesus Christ—is most clearly proclaimed through the preaching of the word. The most important thing, then, is to hear God's word. For this reason Protestant services also include readings from the Bible, usually from both Hebrew scriptures (the Old Testament) and the New Testament. Lutheran, Presbyterian, Baptist, and Methodist sermons often relate a passage of the Bible to events in the life of the congregation. In hearing and trusting the word, one has faith. For Pentecostal churches the sermon is also an occasion for an outpouring of the Spirit. Preaching is intended to evoke a response that shows that the Spirit has manifested itself in the hearers. This response can sometimes be a lifting of the arms with hands outstretched. Sometimes it results in dancing or shaking, shouting, speaking in tongues, and collapsing.
Other elements of the worship service vary from denomination to denomination. Hymn singing plays an important role in many denominations. The order of worship varies somewhat. Reformed churches, for example, begin with a hymn or statement of praise, then a confession of sin, a declaration of pardon, readings from the Bible, and a sermon. The worship service is designed to recapitulate the pattern of creation, sin, and forgiveness. If there is a baptism or the Lord's Supper it is typically celebrated after the sermon. Some churches celebrate the sacraments (sometimes called ordinances) weekly; most do it monthly or quarterly.
Most Protestant churches organize their worship services according to a liturgical calendar. The liturgical calendar is a cycle that recapitulates major events in the life of Jesus and the early Church annually. For many non-denominational and independent churches this consists simply of special celebrations for the Christmas and Easter seasons. Mainline denominations have more detailed liturgical calendars. The events associated with Easter shift in the secular calendar, because the date of Easter is celebrated on the first Sunday after the first full moon after the spring equinox. The events associated with Christmas are fixed, since Christmas is always on December 25. The year is divided into:
