In Luke 24:45, Luke strikingly records that Jesus "opened their mind [singular]", and not (contra many modern translations) "he opened their minds."
Perhaps this hints at the biblical teaching that the church is called to have "one mind," in the sense that we are to grapple together as one body with the teaching of Scripture and seek to make progress in our understanding of God's ways as a body, rather than splintering off on our own, everyone with their own Bible in glorious isolation reaching their own idiosyncratic doctrinal conclusions.
Clearly this involves an awareness of the historical development of our faith. If we never read the Fathers, or the medievals, or the Reformers, then we may as well be cut off from the wisdom of the past. And yet there is another (altogether less trendy in some quarters, but no less vital) way of grappling with the word of God in community, and that's with the people whom God has put alongside us in our churches.
