Christian Augustus was born in Sulzbach in 1622 as the eldest son of Augustus, Count Palatine of Sulzbach and Hedwig of Holstein-Gottorp.^[1] He succeeded his father in August 1632, at the age of 10. Christian Augustus was a tolerant ruler. He granted his citizens the right to choose their Christian denomination and introduced the Simultaneum, whereby churches had both Protestant and Catholic services. In 1666 he permitted Jews to settle in the Duchy of Sulzbach and, due to his interest in mysticism and the Kabbalah, allowed a Hebrew print-shop.^[2] Under his rule, Sulzbach also became an intellectual center and the site of a regionally significant printing industry.

Christian had a close relationship with his granddaughter Sibylle of Saxe-Lauenburg, wife of Louis William of Baden-Baden and Regent of her son's dominions.

Christian Augustus died in Sulzbach in 1708 and was buried in the Church of Sancta Maria in Sulzbach.
