Perry was dunked last month in Little Rocky Creek near the small town of Independence in a private baptism witnessed only by close friends and family. Spokeswoman Lucy Nashed said Tuesday that Perry "wanted to reaffirm his commitment" to his faith in a way that holds great personal meaning.
The baptism was first reported by The Texas Tribune.
The creek is the same one where Houston was baptized before becoming the seventh governor of Texas in 1859.
Perry will leave office in January after a record 14 years on the job. He hasn't ruled out another run for president in 2016.
