Agree that "context" is absolutely needed for proper understanding. But the assertion in OP (and I would argue, 1 Cor 1-4) is that the needed "context" does not extend past the pages of God's revealed Word. You conclude that "evangelism and acceptance" of gospel don't require scholarship (also agree). Then why would remaining true to the gospel (
"that which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ." 1 Jn 1:3) extend beyond that context? —
