The Third Sunday Concert Series is an outreach of Christ Church but is supported in large part by memberships. The Third Sunday concerts feature area musicians and singers, usually on the third Sunday of each month, September to May. All concerts begin at 5 p.m. and are free and open to the public. A major attraction of the series is the wine and hors d’oeuvres reception which follows each concert. Not only is it an opportunity for the audience to meet and talk with the guest artists, but it also provides an opportunity for the audience to visit with friends made over the years of concerts at Christ Church.
During the summer, there are two Third Sunday Concerts held at the Christwood Atrium in July and August. On July 15, the Bayou Liberty Jazz Combo performs July 15 and . On August 19, John Rankin and Harry Hardin will be playing together in concert
