No, being married is no longer a strict requirement to become a seminary teacher in the LDS Church. In recent years, the church has updated its policies to be more inclusive, allowing women with children at home to serve as seminary and institute teachers. Additionally, individuals who have experienced divorce and remarriage are now eligible to be hired as seminary teachers, reflecting a broader acceptance and recognition of diverse life circumstances. These policy changes, announced around August 3, 2017, aim to provide more opportunities for qualified individuals to serve in teaching roles within the church's educational programs, emphasizing the importance of faith, dedication, and doctrinal knowledge over marital status.
