In the reformed tradition, you have to compare scripture with scripture. What some people see as "contradictions" are simply different perspectives of the same event. When you put the two together, you get a more complete picture. Ofcause there are minor details that differ. If you go to court, all the witnesses do not agree to every last detail of an event. In the case of the resurection of Jesus, ofcause there is minor differences in the detail: It was, after all, written some time after the event.
But the proof of the Christian faith is in its very existance. In His ultimate wisdom, God made the birth of Christianity very painful for the apostiles. This way, they can not be suspected of alterier motives. Think about it: They spoke of events they saw with their own eyes. Therefore, they were not speaking about posibilities. What they said, was either true or false, and they would know if it's true or false. Let's us suppose they were lieing. What is the motives? Wealth? certainly not. Paul was a roman citizen and a member of the majority religious party. He was a fanatic against the church, and all of a sudden he became an Apostile. He lost all his earthly possesions and freedoms.Fame? Ofcause not. If they where making it up, and did not really believed in the God they were preaching, there were no Guarantee that the their story of a man rising from the dead would catch on. They would've quit after they suffered the amount of persucution they suffered. For all they knew, chances were that Christianity would die out quickly, and they would be forgotten. I can't think of any other reason for them to persist in such hardships other than that they truely believed in Jesus Christ. What is more is their witnesses were backed up by thousands of other witnesses. The events they talked about, did not happen somewhere in a cave (Like the revelations to Mohammed) it happened out in the open. People knew what they were talking about.
After his resurrection, Jesus apeared to hundreds of people. Surely you can't get hundreds of people to tell exactly the same lie? That is what some people wants us to believe about the moonlandings!
Were they crazy? Go to a nut house and look what you'll find. You won't find 5 crazy people telling the same crazy stories. Crazy people don't work in concert.
There is no other religion that grew under persucution, while the followers did not fight back with violence. This is because their faith is planted by God Himself.
Now that we established the motives of the witnesses, it is save to assume their witnesses are true accounts. But what about Jesus himself? He performed multiple wonders where everyone could see it. There were no supernatural power stronger than Him. In fact: demons in possesed people admitted He was God. And so did He. He practiced what he preached. There is a misconception that only the 12 apostiles followed him. Wrong. most of the time, hundreds, even thousands followed him, hearing every word, and seeing every wonder. You see Christianity is founded on witnesses. Undisputable witnesses, even though their detail differ a bit.
