Traditions of these non-Protestant churches include the Bible, patristic, conciliar, and liturgical texts. The conciliar idea of episcopal government continues in the Eastern Orthodox Church. Gregorio Velasco became the first Vincentian Rector of the conciliar Seminary. That day's agenda included the election of members of the ten conciliar commissions. While the advantages of the conciliar system were obvious, the system also had its disadvantages. From 1784 to 1880, it was the site of Real Seminario Conciliar de San Carlos. "Haec Sancta Synodus" marks the high-water mark of the Conciliar movement of reform.
