Some questions:
Your Signature quote says “Pray the Rosary Every Day” - if you are praying it, then you are claiming “I believe in Jesus Christ,… crucified under Pontius Pilate” when you begin your Rosary.
So, you yourself are claiming and asserting to God, to yourself, and to the world that Jesus was indeed crucified.
Now, if someone told me it was a made up story, and here I was claiming it true every day, and if someone told me it was only in one Gospel, what should I do? Would I stop praying the Rosary? No, the Rosary is True, and my confession of Jesus is True. So, the only thing to do is to go look in the Gospels, all four, and see if the story is true that someone told me. And I will find that the account of the crucifixion is in all four Gospels, so I can go and tell the person that it is not just in one but in all four. And I can tell them Jesus really was crucified.
Then I would do a web search with the question: “How were thieves punished by Rome in 30 AD” And I would find many sites stating that punishment of thieves could be crucifixion or flogging or prison, depending on who the thief was. And I would bring this information to the person who told me, and ask him to stop saying things that he does not know about.
