A 37 (Addendum): Note that both spells may require successful
craft checks,
minor creation in the event of a "complex" item(clarified in the PHB as "Craft (bowmaking) check to make straight arrow shafts"), and
fabricate in the event of "articles requiring a high degree of craftsmanship" (clarified in the PHB as jewelry, swords, glass, crystal, and the like.")
Also, despite the clarifications in the spell descriptions, the Craft skill has different levels of complexity. A complex item is a lock with DC 20, a high-quality item such as a bell is DC 15, a typical item such as an iron pot is DC 10. While the holy symbol is not magical, the Craft DC might preclude successful creation/fabrication.
