***Mark, wasn’t it you who had (has) trouble telling us what the Gospel is?***
No, it was the Reformed side.
I said that the summary of the Gospels is the Lord’s Prayer, the Two Commandments of Jesus, and the Sermon on the Mount.
Your side contended that the summary of the Gospels is “Christ died.”
I think that this is an excellent side by side comparison of the two theologies and justification in itself for choosing Catholic belief over the Reformed.
The best summary of the Gospel is given by Paul in I Corinthians 15:1-4:
"Moreover, brethren, I declare unto you the Gospel which I preached unto you, which also ye have received, and wherein ye stand, by which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
"For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures, and that he was buried, and that he rose again the third day according to the scriptures."
That is the short version of the Gospel, but notice that twice Paul identifies the scriptures as central to the meaning of the Gospel, providing the foundation and context thereof.
What is the Gospel?
We all know there are four books written by Matthew, Mark, Luke and John that are called "The Gospels."
