Suppose a complete well-powered category has enough objects saturated with respect to anodyne morphisms. Inside a saturated object containing A, intersect all strong subobjects containing A. The resulting object is saturated, the map from A to it is anodyne, and its extension property makes it the reflection of A into the full subcategory of saturated objects.
