June 28 is the memorial of St. Irenaeus. Pope Benedict XVI gave a General Audience talk on him that is available here. Amy Welborn wrote a study guide for all of these talks of Pope Benedict, and it is available as a free download here. Sample pages are below.
For Irenaeus, Church and Spirit were inseparable: "This faith", we read again in the third book of Adversus Haereses, "which, having been received from the Church, we do preserve, and which always, by the Spirit of God, renewing its youth as if it were some precious deposit in an excellent vessel, causes the vessel itself containing it to renew its youth also.... For where the Church is, there is the Spirit of God; and where the Spirit of God is, there is the Church and every kind of grace" (3, 24, 1). As can be seen, Irenaeus did not stop at defining the concept of Tradition. His tradition, uninterrupted Tradition, is not traditionalism, because this Tradition is always enlivened from within by the Holy Spirit, who makes it live anew, causes it to be interpreted and understood in the vitality of the Church. Adhering to her teaching, the Church should transmit the faith in such a way that it must be what it appears, that is, "public", "one", "pneumatic", "spiritual". Starting with each one of these characteristics, a fruitful discernment can be made of the authentic transmission of the faith in the today of the Church. More generally, in Irenaeus' teaching, the dignity of man, body and soul, is firmly anchored in divine creation, in the image of Christ and in the Spirit's permanent work of sanctification. This doctrine is like a "high road" in order to discern together with all people of good will the object and boundaries of the dialogue of values, and to give an ever new impetus to the Church's missionary action, to the force of the truth which is the source of all true values in the world.
