You know what that says??? That says Matthew is inspired...And you know how we know that??? Scripture alone..
Would you be kind enough to give us the exact definition of the word "Scripture as found in the Koine Greek.
I wouldn't waste my time trying to find out...There are over 25 Greek lexicons out there...You have no way of knowing which one if any is correct...
PolyCarp alludes to the book of Matthew...Peter recognizes all of Paul's writings as scripture...You guys quote Matthew left and right...Why would you quote it if it is not scripture???
