In Methodism, Mary is honored as the Mother of God. Methodists do not have any additional teachings on the Virgin Mary except from what is mentioned in Scripture and the ecumenical Creeds. As such, Methodists believe that Mary was conceived in her womb through the Holy Ghost and accept the doctrine of the Virgin Birth, although they, along with Orthodox Christians and other Protestant Christians, reject the doctrine of the Immaculate Conception. John Wesley, the principal founder of the Methodist movement within the Church of England, believed that Mary "continued a pure and unspotted virgin", thus upholding the doctrine of the perpetual virginity of Mary. Contemporary Methodism does hold that Mary was a virgin before, during, and immediately after the birth of Christ. In addition, some Methodists also hold the doctrine of the Assumption of Mary as a pious opinion.
