Historic Trinity Sunday School At Historic Trinity Sunday School classes are held each Sunday at 9:30 a.m. for all ages from nursery (0-2) and above in Otte Hall (Parish Hall). The greatest investment we have in life is our children. The time, the love, and spiritual direction we expend during their early years will pay huge dividends in the future. Take time now to lead your children in the way of the Lord. Email: Historic Trinity for additional information about our Sunday School program.
