The Fall of Acre inaugurated Christian theodicy crises blaming Saracen ascendancy on Christian sin

Evidence

Riccoldo addresses the first of his Five Letters on the Fall of Acre to God, expressing his astonishment that he should allow such misfortune to befall Christendom, that he should give such power and glory to the Saracens. The Saracens, Jews, and Tartars mock us, asking, “Where is the God of Christians?” taunting Christians who thought that Jesus son of Mary was God and that he would help them. — John V. Tolan, Saracens, 1239
