"The Sacred Writings Of ..." provides you with the essential works among the Early Christian writings. The volumes cover the beginning of Christianity until before the promulgation of the Nicene Creed at the First Council of Nicaea. Cyril of Jerusalem was a distinguished theologian of the early Church (ca. 313 - 386). He is venerated as a saint by the Roman Catholic Church, the Eastern Orthodox Church, and the Anglican Communion. In 1883, Cyril was declared a Doctor of the Church by Pope Leo XIII. He is highly respected in the Palestinian Christian Community. (courtesy of wikipedia.com) His famous twenty-three catechetical lectures, which he delivered while still a presbyter in 347 or 348, contain instructions on the principal topics of Christian faith and practice, in rather a popular than a scientific manner, full of a warm pastoral love and care for the catechumens to whom they were delivered. Each lecture is based upon a text of Scripture, and there is an abundance of Scriptural quotation throughout. After a general introduction, eighteen lectures follow for the competentes, and the remaining five are addressed to the newly baptized, in preparation for the reception of Holy Communion. These last instructional addresses are called mystagogic, because they deal with the mysteries i.e. Sacraments of Baptism, Confirmation and the Eucharist.
