The world has seen upon the throne greater captains, more profound politicians, vaster and more brilliant intellects, princes who have exercised, beyond their own lifetime, a more powerful and a more lasting influence than St. Louis; but it has never seen a rarer king, never seen a man who could possess, as he did, sovereign power without contracting the passions and vices natural to it, and who, in this respect, displayed in his government human virtues exalted to the height of Christian.  For all his moral sympathy, and superior as he was to his age, St. Louis, nevertheless, shared, and even helped to prolong, two of its greatest mistakes; as a Christian he misconceived the rights of conscience in respect of religion, and, as a king, he brought upon his people deplorable evils and perils for the sake of a fruitless enterprise.  War against religious liberty was, for a long course of ages, the crime of Christian communities and the source of the most cruel evils as well as of the most formidable irreligious reactions the world has had to undergo.  The thirteenth century was the culminating period of this fatal notion and the sanction of it conferred by civil legislation as well as ecclesiastical teaching.  St. Louis joined, so far, with sincere conviction, in the general and ruling idea of his age; and the jumbled code which bears the name of Etablissements de Saint Louis, and in which there are collected many ordinances anterior or posterior to his reign, formally condemns heretics to death, and bids the civil judges to see to the execution, in this respect, of the bishops’ sentences.  In 1255 St. Louis himself demanded of Pope Alexander IV. leave for the Dominicans and Franciscans to exercise, throughout the whole kingdom, the inquisition already established, on account of the Albigensians, in the old domains of the Counts of Toulouse.  The bishops, it is true, were to be consulted before condemnation could be pronounced by the inquisitors against a heretic; but that was a mark of respect for the episcopate and for the rights of the Gallican Church rather than a guarantee for liberty of conscience; and such was St. Louis’s feeling upon this subject, that liberty, or rather the most limited justice, was less to be expected from the kingship than from the episcopate.  St. Louis’s extreme severity towards what he called the knavish oath (vilain serment), that is, blasphemy, an offence for which there is no definition save what is contained in the bare name of it, is, perhaps, the most striking indication of the state of men’s minds, and especially of the king’s, in this respect.  Every blasphemer was to receive on his mouth the imprint of a red-hot iron.  “One day the king had a burgher of Paris branded in this way; and violent murmurs were raised in the capital and came to the king’s ears.  He responded by declaring that he wished a like brand might mark his lips, and that he might bear the shame of it all his life, if only the vice of blasphemy
