2.1 Sovereign Claim
Article 19 - Divine Savior
Canon 5514 (link)
Within some cultures, the proof of the Claim of Divine Savior might emphasize the test and trial of the candidate as in some ancient warrior cultures where success at mortal combat was part of the proof of a worthy ruler. In others, the interpretation of prophecy and revelation is a greater emphasis in selection.
Canon 5516 (link)
While a culture may have developed safeguards to ensure less than optimum candidates were selected through the method of Claim of Divine Savior, the nature of proving such claim historically has left open the risk of abuse through interpretation of prophecy or revelation by the priest class and the minimizing of competition through skewing physical trials or tests.
