The Assembly of Yahweh is a small evangelical Christian church based in Cisco, Texas, emphasizing strict adherence to biblical teachings, including observance of the seventh-day Sabbath and certain Old Testament practices. The congregation focuses on biblical teaching, community outreach, Bible study, and fostering a close-knit faith community. It is notably affiliated with Farris Wilks, a Texas-based billionaire and co-founder of the fracking company Frac Tech, who along with his brother Dan Wilks, has used his wealth to support conservative Christian initiatives. The church serves as a spiritual hub for the Wilks family and their associates, reflecting their commitment to evangelical values and philanthropy in religious causes.

Founded by members of the Wilks family, the church operates independently but aligns with broader networks of conservative Christianity in the United States. It promotes teachings on end-times prophecy, moral conservatism, and personal salvation, often through services, retreats, and local ministry programs. While not a large denomination, its influence extends through the financial and political connections of its prominent members, including donations to other faith-based organizations and advocacy groups. The Assembly of Yahweh remains a low-profile entity, primarily serving the local community in Eastland County, Texas.

The church has no major public controversies documented, but its ties to the Wilks brothers place it within networks of influence involving conservative politics and religious funding. Farris Wilks' involvement underscores the organization's role in private philanthropy, with the brothers known for channeling billions into Christian causes, including media, education, and political action committees.
