Is Matthew or Luke in error?
>>That is not the question here...<<
Yes, it is. You said they both lead to Joseph. The one says from Nathan, the other says from Solomon. You can’t have it both ways.
>>Why do you insist on accepting/using writings that directly contradict what Scripture says to support a belief that is not clearly stated in Scripture?<<
It completely supported scripture unless you assert that either Matthew or Luke are in error. You can’t have it both ways.
It is not up to me to explain the error based on Sola Scriptura as I can accept that there may be minor differences in the accounts.
It is what it is, CB.
Scripture does not say that either lineage is that of Mary and both say they are of Joseph. One must look to extra Biblical sources to support that Heli was Joseph’s father in law.
Do you deny that both lineages list Joseph as the descendent of David and neither list Mary? Do you deny that the NT specifically says that Joseph is the one of the house of David and never says that about Mary?
Where does Scripture say that the line must come through Mary? And where does it say that it does?
Truth is, it doesn’t. One must depend on the OT and extra Biblical writings to support this belief that is not clearly stated in the NT.
So, it is not me who wishes to have it both ways. It is the one who accepts this even though Scripture does not say it and then points to a non Scriptural record to support it when excoriating Catholics who have done the same.
