I listened to some of this debate live, but I just set some time aside now to listen through the whole thing. I must say, you did appear to be agitated at times while Matthew was as cool as a cucumber. I have to admit, he handled himself quite well.
Be that as it may, I don't believe you lost the debate. It was pretty even keeled. A draw, in my estimation.
One bit of friendly advice, the lord mentioned in 2 Cor 3:16, that lord is Jesus.
Nevertheless when it shall turn to
the Lord
, the vail shall be taken away. 2 Cor 3:16
Just 7 verses later, Paul states this:
For
we preach
not ourselves, but
Christ Jesus the Lord
; and ourselves your servants for Jesus' sake. 2 Cor 4:5
Romans 7:4 basically nullifies his argument. In addition, there are many more verses, some that you mentioned, which equally do the same.
I was like, "Come on, dude.", when he said he circumcised all 3 of his sons on the 8th day.
By doing what he is doing, he's putting himself under the curse, per Gal 3, which is very unwise.
You mentioned that you are having another debate. Who is it with and when?
