The debated doctrine of scriptural corruption divides along geographic and religious fault lines

Evidence

On the Islamic side the protagonist of the literal interpretation of tahrif, i.e. that Christians had literally forged the Gospel, Abd: Muhammad “Ali ibn Hazm (d. 1064), was a Spaniard, so that it is not surprising to find that Spanish Christians (followed by Ricoldo), argued against literal forgery, superfluously, as it may seem to us. — Norman Daniel, Islam and the West, 1967

Categorization

• DEFINE: Defines tahrif as the Islamic claim that Christians literally forged the Gospel, contrasting it with the figurative reading.
• QUESTION: Why does the tahrif debate take a geographic shape — Spanish Muslim vs. Spanish Christian? Worth chasing the Iberian polarization mechanism.
