Jove sports," says Heraclitus. For what other employment is seemly for a wise and perfect man, than to sport and be glad in the endurance of what is good, and, in the administration of what is good, holding festival with God? That which is signified by the prophet may be interpreted differently,—namely, of our rejoicing for salvation, as Isaac. He also, delivered from death, laughed, sporting and rejoicing with his spouse, who was the type of the Helper of our salvation, the church, to whom the stable name of endurance is given; for this cause surely, because she alone remains to all generations, rejoicing ever, subsisting as she does by the endurance of us believers, who are the members of Christ. And the witness of those that have endured to the end, and the rejoicing on their account, is the mystic sport, and the salvation accompanied with decorous solace which brings us aid.

For Jesus rose again after His burial, having suffered no harm, like Isaac released from sacrifice. And in defence of the point to be established, I shall adduce another consideration of the
