When his father-in-law, Álvaro de Montalbán, was accused of secretly returning to Judaism in 1525, the Inquisition refused to allow Rojas to act as defending lawyer, but this was evidently on account of Rojas's status as a converso rather than from any suspicion that he might be secretly practising Judaism.
Kada je njegov tast, Alvaro de Montalban, bio optužen za tajni povratak judaizmu 1525. godine, inkvizicija nije dozvolila Rohasu da mu bude advokat, ali to je očigledno bilo zbog statusa Rohasa kao „preobraćenog”, a ne zbog sumnje da bi tajno mogao da se bavi judaizmom.
