Good day Gottle! You seemed a little distraught over inerrancy, so I thought I’d put some things together for you to think about, to encourage you in your walk with God…
ISTM that that to insist on inerrancy warps the Bible into being an error-free body of written signs, at the cost of draining away the Christ-centred significance that gives it life & power.
Based on what you wrote here, about how you felt that total inerrancy drains away the Christ-centered significance of Scripture, I thought you might enjoy pondering the following point made by Pius XII and picked up on by John Paul II:
“The strict relationship uniting the inspired biblical texts with the mystery of the incarnation was expressed by the Encyclical Divino Afflante Spiritu in the following terms: ‘Just as the substantial Word of God became like men in every respect except sin, so too the words of God, expressed in human languages, became like human language in every respect except error’ (EB, n. 559). Repeated almost literally by the conciliar Constitution Dei Verbum (n. 13), this statement sheds light on a parallelism rich in meaning” (JP II address to the PBC, 1993).
A train time-table may be totally inerrant - that doesn’t make it a gospel.
You are correct. Inerrancy doesn’t make Scripture, Scripture. Having God as it’s author is what makes Scripture, Scripture, and what also secures inerrancy. As Pillar of Truth mentioned,
God is held by the Church to be the primary author of Scripture, and God cannot be the author of error.
A declaration of this truth comes from Vatican I: “These books the church holds to be sacred and canonical not because she subsequently approved them by her authority after they had been composed by unaided human skill,
nor simply because they contain revelation without error, but because, being written under the inspiration of the Holy Spirit, they have God as their author, and were as such committed to the church” (Ch. 2, On Revelation). This divine revelation, this inerrancy, under the authorship of God, extends to all of Scripture: “In composing the sacred books, God chose men and while employed by Him they made use of their powers and abilities, so that with Him acting in them and through them, they, as true authors, consigned to writing
everything and only those things which He wanted” (DV, 11).
TI has no specifically Christian significance - the Nativity narratives do: so why need they be TI?
Why historically accurate…
Before moving on, I want to quote the following from Dei Verbum: “Holy Mother Church has firmly and with absolute constancy held, and continues to hold, that the four Gospels just named,
whose historical character the Church unhesitatingly asserts, faithfully hand on what Jesus Christ, while living among men, really did and taught for their eternal salvation until the day He was taken up into heaven (see Acts 1:1)” (19).
Keeping this in mind, you may enjoy thinking about the relationship that exists between the historical facts mentioned in Scripture and the divine significance resting on and present in those facts, as expressed here by the Congregation for the Doctrine of the Faith:
“The Christian faith has its specificity, primarily in that it refers to historical events, or better to a coherent history, which actually took place as history. In this sense, the question about the fact, the reality of the event, is essential to it, and must make room for the historical method. But these historical events have meaning for the faith only because it is certain that in them God Himself acted in a specific way and the events contain something which surpasses simple historical facticity, something which comes from elsewhere and gives them meaning for all times and for all people.
This surpassing element must not be separated from the facts, it is not a meaning which is subsequently added to them from without, but rather it is present in the event itself, and yet it transcends the purely factual aspect” (Current Doctrinal Relevance of the Catechism, 2002).
Benedict XVI writes something similar to this in his book,
Jesus of Nazareth.
I hope this comes as a blessing to you. Happy pondering!

And may the Lord be with you!
