Magnolia's churches grew over the nineteenth and twentieth centuries through new congregations, rebuilding, relocation, and expansion. Magnolia Baptist Christians first traveled to Somerdale or Haddonfield until a chapel and Sunday school were built in 1891, the Magnolia Baptist Church was formally recognized in 1894, moved to Lincoln and Camden Avenues in 1922, expanded through the following decades, reached its greatest membership growth by 1955, and closed in 2000. The Magnolia United Methodist Church, the first church building in Magnolia, was erected in 1815 on land bought from Thomas Barrett, rebuilt in 1859 after an 1858 fire, and later added a parsonage in 1964 and an educational building in 1972; its burial ground includes veterans of the Revolutionary War and Civil War. Mount Olive Baptist Church began as a mission church, was organized in 1923 and chartered in 1931, was relocated to the Lamott family home site, suffered a fire on Palm Sunday 1956, and rebuilt in time to hold services in December 1956. Christ Episcopal Church began with home services in 1901, moved to the Magnolia Fire Hall, dedicated its church building in 1914, expanded its facilities after 1964, and improved the building again in 1995. St. Gregory's R.C. Church was incorporated in 1951 as a mission to St. Rose of Lima, completed its church and rectory in 1955, added a school and convent in 1964, closed the school in 1981, and remained an active landmark in Magnolia. Holy Trinity Evangelical Lutheran Church was organized in 1893, dedicated its first building in 1894, adopted its official title in 1943, moved to West Evesham Road in 1945, and dedicated new parish and church buildings in 1953 and 1957.
