First United Methodist Church of Sinton has served the community since the early 20th century, with roots in earlier interdenominational worship. Between 1894, when the charter for Sinton Town Company was granted, and 1908, the town had no organized Protestant church, but Christians met regularly for worship and were ministered to by visiting pastors of different denominations, while Methodist lay leader W.T. Barnhouse served when no ordained Methodist minister was available. In 1907, the Sinton Town Company resolved to donate one lot to any group wishing to build a church, and members of the Church of Christ accepted the offer and erected the first Protestant church building in Sinton, where alternating preachers and denominational services continued. In 1908, Sinton Methodists organized and built their first church that same year. The church developed a long record of community service, with women playing a driving role by holding events to raise donations and funds. Though itself once damaged by flooding, the church also gave to others who suffered from floods, and its members assisted Sinton residents through community health, food ministry, and child education programs. Pastors including the Rev. J.J. Mason led the church as it grew, members entered fulltime ministry and supported overseas missionaries, and the church continues to provide for the spiritual, physical, and educational needs of the Sinton community.
