According to the church's website: "The four oval paintings on the reredos date from the early 18th century and originated in Colonial Mexico. The painting at the top left is St. Teresa of Avila; on the bottom left is St. Francis of Assisi. At the top right is St. Gertrude of Germany; on the bottom right is St. Louis IX, King of France."
