I just want to make a quick observation and leave a link for public benefit. John Davenant, 17th cent. Bishop of Salisbury, has this to say about the original apostles of Christ:

Wherefore when the Prophets, and Apostles are adorned with this honorable Title, it is rather to be referred to their saving Doctrin concerning Christ, than to their own particular Persons. The power of these was far greater than that of their succeeding Ministers, because they were so enlightned, and governed by the holy Spirit, that they could not at all erre, either in Preaching, or Writing. Therefore we acknowledge their Doctrine, as the Doctrine of God and Christ, certaine, infallible, and wholly Divine, with Tertullian, that saith, There is no Divine Word but of God alone. Which Word was thundred both by the Prophets, by the Apostles, by Christ himselfe.

We see a few important things here. For Davenant, the apostles’ chief honor and authority is their doctrine. Their power was “far greater” than their successors here. The Apostles were so governed by the Holy Spirit that they were infallible and inerrant in their preaching and writing.

The Apostles are therefore unique in this way. Their successors do not have the same power or status. And the Apostle’s gift of inerrancy applied to their writings. Therefore, the New Testament is inerrant.
