The ordination procedure set down in the Buddha's time resembles that of a collegiate Greek-letter fraternity in an American university, with a secret vote of the other members to pass on the ordinand's application, the black-ball system. While realistically, all his qualifications have been studied and passed on beforehand, there is still in the ordination procedure a somewhat atrophied interrogation in memorized Pali to make sure there are on impediments to ordination. If you want to follow one of these services, acquire a copy of Ordination Procedures, which has Pali- English translations.
