Undesigned coincidences without circularity: How do you do that?

Last time I gave a series of undesigned coincidences that confirm the reliability of Acts, using three of what are known as the undisputed Pauline epistles--I and 2 Corinthians and Romans.  But what good are undesigned coincidences in arguing for the reliability of Acts if they come from epistles that skeptical scholars dispute the authorship of, like 2 Timothy? Is it necessary to first get strong separate evidence that an epistle was written by Paul before it can provide any evidence for the reliability of Acts, even by an undesigned coincidence?  Nope. An undesigned coincidence provides simultaneous evidence for the authenticity of a document (that is, it's authorship by the person it claims to be written by) and for the authenticity and reliability of an historical document like Acts that it intersects with. How is that possible? Isn't that circular? Nope. Watch to find out why.

Here is an earlier presentation I did on mutual support that makes a similar point.  https://youtu.be/SqkNJ497VJo
