The miraculous Jesus was something religious scholars had to lobby as canonical for centuries before it was officially recognized.

This is just flat out false. The gospels were still written within the first century and even then, the oldest letter - The epistle to the Galatians - still testifies that Jesus rose from the dead.

Galatians 1:1-5, 12, 15-16 ESV [1] Paul, an apostle—not from men nor through man, but through Jesus Christ and God the Father, who raised him from the dead— [2] and all the brothers who are with me, To the churches of Galatia: [3] Grace to you and peace from God our Father and the Lord Jesus Christ, [4] who gave himself for our sins to deliver us from the present evil age, according to the will of our God and Father, [5] to whom be the glory forever and ever. Amen.

[12] For I did not receive it from any man, nor was I taught it, but I received it through a revelation of Jesus Christ.

[15] But when he who had set me apart before I was born, and who called me by his grace, [16] was pleased to reveal his Son to me, in order that I might preach him among the Gentiles, I did not immediately consult with anyone;

(1 Thessalonians is a contestant for the oldest, but still)

1 Thessalonians 1:10 ESV

[10] and to wait for his Son from heaven, whom he raised from the dead, Jesus who delivers us from the wrath to come.

The letters carry a miraculous nature

1 Corinthians 15:3-8 ESV

[3] For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, [4] that he was buried, that he was raised on the third day in accordance with the Scriptures, [5] and that he appeared to Cephas, then to the twelve. [6] Then he appeared to more than five hundred brothers at one time, most of whom are still alive, though some have fallen asleep. [7] Then he appeared to James, then to all the apostles. [8] Last of all, as to one untimely born, he appeared also to me.

If you got rid of the Gospels and revelation in the New Testament, the Faith remains mainly the same.

But that's besides the point, trying to claim miracles can't happen because it's impossible is an oxymoron. If it was able to happen without supernatural means, it wouldn't be a miracle.
