On August 29, 1898, seven students of Christian Science met and organized as First Church of Christ, Scientist, in West Chester, Pennsylvania, inviting to join with them nine other persons who were known to be interested in this teaching. Prior to this, Sunday morning services in the form prescribed for all Christian Science churches had been held in private houses for some two or three years, and Friday evening experience meetings, as they were called, had been held for about, a year. After the organization of the church, regular services were held in Library Hall on Sunday mornings and Wednesday evenings. From September 1, 1902, they were held in rooms located at 117 North High Street. A reading room was also established there in connection with the church, and has been maintained ever since. In November, 1906, a Sunday school was opened with one class, which has now grown to four classes, having from five to nine children each.
During the period in which The Mother Church was being erected at Boston, this church contributed the collections taken on the first Sunday of each month to The Mother Church building fund, and after notice was received that no more contributions Were desired, the collection taken on the first Sunday of each month was set aside for a home church building fund. At the annual meeting of members of this church, November 7, 1908, it was decided to procure a lot suitable for the construction of an edifice, and a committee was appointed for that purpose.
Application was made to the Court of Common Pleas of Chester County for a charter, which was granted on June 28, 1909. This was the first charter granted to a Christian Science church in Pennsylvania after the adverse ruling of the supreme court upon the application of the Philadelphia church. In the same month the ground was broken for the structure, and on August 19, 1909, the corner stone was laid with a simple service held at half past six in the morning. The edifice was finished in March, 1910. The board of trustees held their monthly meeting in the new building for the first time on March 5 and on Sunday, March 6, the first church service was held there. During the year 1915 a pipe organ, electrically controlled, was installed. The organ was the outcome of an initial gift of five hundred dollars made for this special purpose.
