If the Apostles Peter and Paul didn't advocate for what Justin Martyr asserted, I find it hard to believe it was what God meant to teach AFTER their death. God is NOT done with the nation of Israel. He declared:
This is what the Lord says, he who appoints the sun to shine by day, who decrees the moon and stars to shine by night, who stirs up the sea so that its waves roar— the Lord Almighty is his name:
“Only if these decrees vanish from my sight,” declares the Lord, “will Israel ever cease being a nation before me.” declares the Lord.
This is what the Lord says: “Only if the heavens above can be measured and the foundations of the earth below be searched out will I reject all the descendants of Israel because of all they have done,” (Jeremiah 31:35-37)
God is not a man that He should lie.
Amen, Amen, Amen!
If we are going to make Scripture the rule of our faith (Sola Scriptura) then we have to be willing to look at what is taught and question it. A lot of churches teach Supersessionism so from a very early age we just accept it as true.
God is not a man that He should lie.
Not the one true God we worship.
