This latter provision was derived from the imperial legislation against treason, which disabled children of traitors from holding office and succeeding to collateral estates.[492] Frederic II, in his Ravenna decree of 1232, made this applicable to the children and grandchildren of heretics, which was eagerly incorporated into the legislation of Alexander IV and Honorius IV, although Boniface VIII mitigated it slightly by exempting grandchildren in the female line.[493] As part of the canon law this of course governed the Spanish Inquisition and, if there were those who questioned the justice of punishing orthodox children for their parents' heresy, they were triumphantly silenced by Alfonso de Castro, who pointed to Original Sin as an irrefragable proof that this was in accordance with the law of God.[494] The application of these restrictions to reconciled penitents apparently originated with the Council of Béziers, in 1246, which ordered that penitents should not hold public office, or serve as physicians or notaries, or wear silk garments or gold and silver ornaments or other vanities--in short, that their apparel should befit those whose lives constructively were to be passed in repentance.[495] These provisions were not carried into the canon law but apparently became traditional in the Holy Office. In the Instructions of 1484 there is nothing said as to the disabilities of descendants, but inquisitors were instructed to order penitents, after completing their penance, never to hold public office or benefices or to serve as procurators, tax-collectors, farmers of the revenue, grocers, apothecaries, physicians, surgeons, bleeders or brokers, thus prohibiting the professions which they had specially made their own. Moreover, they were not to wear gold or silver, coral, pearls or other precious stones or garments of silk or camlet or other finery or to ride on horse-back or bear arms, and all this during life, under penalty of relapse.[496]
