Yes, it is a matter of hermeneutics, and more fundamentally, a matter of faith. Rev. Harrison wrote, "If I reject what Scripture teaches as history about creation, why should I not then reject everything else (including the resurrection itself) that appears contrary to reason?"
Because the latter does not necessarily follow from the former.
"'If the Bible is wrong about creation, there is no Gospel. It's as simple as that.' [No, it's not that simple.] that if one Biblical doctrine such as a literal 6-day/24 hour creation fell, your faith would fall because one's faith is based on a conviction that the Scriptures are the inspired and inerrant word of God (a Fundamentalist view) rather than the other way around (the Lutheran view), that, coming to faith through the Gospel, we then confess an inerrant Scripture."

"The truthfulness of the Gospel does not depend upon the inerrancy of the Scriptures. [footnote 13]
and,
"Relative to the role of the Gospel as norm in the Scriptures, however, it is important to observe that it is one thing to say that it is contrary to the Holy Spirit's intent when Scripture is interpreted in such a way that the Gospel is obscured; it is quite another thing to say that since the Holy Spirit's intent in the Scriptures is to proclaim the Gospel, it was never His intent that His Word in Genesis 1-11, for instance, should be understood as relating facts of history, or to say that in view of "the perpetual aim of the Gospel" (AC XXVIII, 66; Latin) apostolic directives for the church's life may be set aside. It is one thing to search the Scriptures to discover ever more fully how they witness to Christ and relate to His Gospel; it is quite another thing to explore the implications of the Gospel for freedom in handling the Scriptures. The interest of one is to see the richness and the glory of the Gospel to aid preaching; the interest of the other is to explain the alleged limitations and flaws of the Bible in a way that avoids the embarrassment of defending it as God's very own inerrant Word while at the same time upholding and affirming its authority. The Gospel is the norm in the Scriptures in the sense that it absolutely prohibits understanding any passage to teach salvation by works. It is not norm in the sense that the center of Scripture becomes a device to sanction a view of the Bible and a method of interpreting it which virtually denies that the whole Bible is God's inspired, authoritative Word on all matters concerning which it speaks."

I recall Andy Bartelt's class, when a portion of OT Scripture seemed to be in error. Upon further examination of the Hebrew, however, it was properly explained. Bartelt's quip, "Whew! Almost lost my faith for a minute there!"
