In response to the disarray of religious educational institutions Pope Leo XIII in his encyclical "Aeterni Patris" of 4 August 1879 called for the renewal of Christian philosophy and particularly the doctrines of Aquinas:We exhort you, venerable brethren, in all earnestness to restore the golden wisdom of St. Thomas, and to spread it far and wide for the defense and beauty of the Catholic faith, for the good of society, and for the advantage of all the sciences. Pope Leo XIII's encyclical "Aeterni Patris" of 1879 was a great impetus to the revival of neo scholastic Thomism. On 15 October 1879 Leo created the Pontifical Academy of St. Thomas Aquinas and ordered publication of a critical edition of the complete works of the "doctor angelicus". Superintendence of the "leonine edition" was entrusted to Zigliara. Leo also founded the "Angelicum's" Faculty of Philosophy in 1882 and its Faculty of Canon Law in 1896. The College began once again to gain status and influence. Under Pope Leo XIII Zigliara contributed to the encyclicals "Aeterni Patris" and "Rerum novarum".
