The mission of Christ Jesus, climaxed by his resurrection and his ascension above materiality, was the good news of the first century of the Christian era. It was told and retold by apostle and disciple. Churches began to be established whose members healed the sick and raised the dead.
A number of these churches arose in Asia Minor, where Paul's early missionary travels were so effective. The beloved disciple John likewise had a part in contributing to the spirituality which characterized these early Christian churches. In the second and third chapters of the Book of Revelation appear the messages that he sent to the churches in Asia Minor, messages which are applicable today as Christian Science churches, whose members likewise practice Christian healing, spring up in many parts of the world.
The verse, "He that hath an ear, let him hear what the Spirit saith unto the churches," appears in each of these messages. Mrs. Eddy's definition of "ears" reads, "Not organs of the so-called corporeal senses, but spiritual understanding" (Science and Health, p. 585). The messages in the Book of Revelation are, therefore, addressed to all in every age who have any degree of spiritual understanding.
