Medieval Castile linked apostasy to Muslims with military treason and defection

Evidence

The Partidas further specifies that apostates may be accused up to five years after their death, and only those who have “rendered some great service to the Christian religion” may escape punishment. This last stipulation shows again the political context of apostasy: it allows rebels who have gone over to Castile’s Muslim enemies to return to Castilian society in exchange for some “great service”—presumably either military intelligence or military service. — John V. Tolan, Saracens, 984
