No other settled place of worship than the Friends's meeting existed in Gwynedd until the Revolution……..About 1772, however, a movement had begun to build a church in Gwynedd, for the joint use of the Lutheran and German Reformed members. …..
The next pastor was Rev. George Heilig. He began October 22, 1826, and continued until 1843, the longest pastorate in the history of the church. During his time an organ was introduced into church service; Samuel Kneedler was organist, and Abraham Danehower was leader of the choir. Hitherto the service had been all in the German language, but the necessity of English service was now recognized, and the pastor introduced it. For a time he officiated alternately in each language. During this pastorate the Sunday-school was organized, of which some notes are given below. Mr. Heilig went from here to Hamilton, Monroe County, Pennsylvania, and died at Catasauqua, in September, 1869.
