no major services linked to the work of Christ. However, this is not to say that the Jewish services were copied or deliberately substituted, see Supersessionism. With respect to attire worn at church services, Christians have historically tended to wear modest clothes (cf. ). Men have traditionally removed their caps while praying and worshipping, while women have traditionally worn a headcovering while praying and worshipping (cf. ). These practices continue to be normative in certain churches, congregations, and denominations, as well as in particular parts of the world, such as in Eastern Europe and in the Indian subcontinent, while in the West, attention to these observances has waned generally (apart from those denominations that continue to require them, such as Conservative Anabaptist churches). In many nondenominational Christian churches, it may be customary, depending on the locality, for people to be dressed casually. Contemporary church services Contemporary worship services have their origins in the Jesus Movement of the 1960s. In the 1980s and 1990s, contemporary Christian music, comprising a variety of musical styles, such as Christian rock and Christian hip-hop was adopted by evangelical churches. Over the years, the organs have been replaced by pianos, electric guitars and drums. These contemporary worship services feature a sermon based on the Bible. Worship service in Evangelical churches is seen as an act of God's worship. It is usually run by a Christian pastor. It usually contains two main parts, the praise (Christian music) and the sermon, with periodically the Lord's Supper. During worship there is usually a nursery for babies.

With the 1960s' charismatic movement, a new conception of praise in worship, such as clapping and raising hands as a sign of worship, took place in many evangelical denominations. In the 1980s and 1990s, contemporary Christian music, including a wide variety of musical styles, such as Christian Rock and Christian Hip Hop, appeared in the praise. In the 2000s and 2010s, digital technologies were integrated into worship services, such as the video projectors for broadcasting praise lyrics or video, on big screens. The use of social media such as YouTube and Facebook to retransmit live or delayed worship services, by Internet, has also spread. The offering via Internet has become a common practice in several churches. In some churches, a special moment is
