On Friday of the Second Week of Lent our Church invites us to first read and reflect on a passage from the book of Exodus (19:1-19; 20:18-21) entitled "The promise of the covenant and the revelation of the Lord on Mount Sinai)". Our treasure, which follows, is from a treatise Against Heresies by Saint Irenaeus, bishop.
Saint Irenaeus was a late second century Greek bishop noted for his role in guiding and expanding Christian communities in the southern regions of present-day France and, more widely, for the development of Christian theology.
On Jan. 21, 2022, Pope Francis named a Saint Irenaeus as a Doctor of the Church. Although he has just now been named a doctor of the Church, St. Irenaeus has always been known as a brilliant and orthodox teacher of the faith. The documents of the Second Vatican Council cite 14 references to his work, and the Catechism of the Catholic Church cites him 29 times.
Pope Francis assigned St. Irenaeus the title "doctor of unity" for his efforts to unite the Church, which was competing against the heresy of Gnosticism. Gnosticism taught that the world was created and ruled by a lesser divinity, the demiurge, and that Christ was an emissary of the remote supreme divine being, esoteric knowledge (gnosis) of whom enabled the redemption of the human spirit.
St. Irenaeus might also be the first doctor of the Church to die as a martyr. St. Irenaeus is known mainly for his clear and systematic teaching of the Christian faith because he considered the role of a bishop primarily as a teacher. He was particularly interested in apostolic succession, and he produced one of the earliest lists of the first bishops, going back to the time of the Apostles.
He is most known, though, for his treatises Against All Heresies, written about the year 180. Most of these heresies, as already mentioned, were from Gnosticism. He clearly understood the need to articulate the orthodox faith taught by the Apostles and against those who promoted other ideas that threatened the Apostles' teachings. All this was more than 100 years prior to the Council of Nicaea, which began to codify Christian dogma.
Saint Irenaeus was the last known living connection with the apostles. He is the earliest surviving witness to regard all four of the canonical gospels as essential.
Against Heresies is a work of Christian theology written in Greek about the year 180 by Irenaeus, bishop of Lyon in France. In it, Irenaeus identifies and describes several schools of Gnosticism, and other schools of Christian thought, whose beliefs he rejects as heresy. He contrasts them with orthodox Christianity.
The second book of the Pentateuch is called Exodus, from the Greek word for "departure," because its central event was understood by the Septuagint's translators to be the departure of the Israelites from Egypt. Its Hebrew title, Shemoth ("Names"), is from the book's opening phrase, "These are the names…." Continuing the history of Israel from the point where the Book of Genesis leaves off, Exodus recounts the Egyptian oppression of Jacob's ever-increasing descendants and their miraculous deliverance by God through Moses, who led them across the Red Sea to Mount Sinai where they entered a covenant with the Lord. Covenantal laws and detailed prescriptions for the tabernacle (a portable sanctuary foreshadowing the Jerusalem Temple) and its service are followed by a dramatic episode of rebellion, repentance, and divine mercy. After the broken covenant is renewed, the tabernacle is constructed, and the cloud signifying God's glorious presence descends to cover it.
These events made Israel a nation and confirmed their unique relationship with God. The "law" (Hebrew torah) given by God through Moses to the Israelites at Mount Sinai constitutes the moral, civil, and ritual legislation by which they were to become a holy people. Many elements of it were fundamental to the teaching of Jesus as well as to New Testament and Christian moral teaching.
