In 2005, the church installed 32-rank Moeller pipe organ in the new sanctuary. The organ was originally built for First Baptist Church in Kalamazoo, Michigan. When that church decided to replace its organ with a new instrument, TCPC purchased the Moeller and sent a team of volunteer workers to Michigan to remove it from its original home. The organ was beautifully restored by P. J. Swartz Pipe Organ Services of Eatonton, Georgia. It is a classic American instrument in the symphonic tradition that characterized many organs of that era. Because the specifications were designed for a wide variety of literature, it has been used for an array of eclectic styles. The organ is enclosed in three chambers, all under expression, unusual for most organs. All three chambers are positioned for maximum acoustical effect along the back of the 65-seat choir loft. The organ is ideally suited for an evangelical church that has many kinds of functions, ranging from formal worship services to conferences and community concerts.

The organ was dedicated by Dr. Joyce Jones on October 30, 2005 (Reformation Sunday). A standing room only crowd filled the sanctuary. The program may be viewed below.
