Church attendance is a central religious practice for many Christians; some Christian denominations, such as the Catholic Church require church attendance on the Lord's Day (Sunday); the Westminster Confession of Faith is held by the Reformed Churches and teaches first-day Sabbatarianism (Sunday Sabbatarianism), thus proclaiming the duty of public worship in keeping with the Ten Commandments. Similarly, The General Rules of the Methodist Church also requires "attending upon all the ordinances of God" including "the public worship of God". The Lutheran Christian theologian stated that church attendance is the "foundation for the Christian life" as "the Christian Bible and the sacraments provide the framework for the faith"; he also states that it is important for believers because it aids in the prevention of backsliding, as well as offers "the company of other believers". Until 1791, the government of the United Kingdom required attendance at church services of the Church of England (the mother Church of the Anglican Communion and a state Church) at least twice a year. In addition to being based upon the spirit of the Ten Commandments, the importance of church attendance in Christian theology is delineated in , which implores the believers: "Let us not neglect our church meetings, as some people do, but encourage and warn each other, especially now that the day of his coming back again is drawing near." About two-thirds of Latin American Christians and 90% of African Christians (in Ghana, Nigeria, Rwanda and Zimbabwe), according to the World Values Survey, said they attended church regularly. South Africa is the only African country where just 55% of people attend church regularly. According to a 2018 study by the Pew Research Center, Christians in Africa and Latin America and the United States have high levels of commitment to their faith. Data from the European Social Survey in 2012 showed that around a third of European Christians said they attend services once a month or more. The Gallup International, a self-reporting survey conducted via telephone, indicates that 37% of Americans report that they attend religious services weekly or near-weekly in 2013. The Pew Research Center stated, however, that there is a "sharp increase in church attendance around the two most significant Christian holidays, Christmas and Easter."
