It is possible to influence a buddhist by discussing Christianity.
The crucifixion is required for man to be saved by Christian beliefs. Yes, there can be Christianity without the crucifixion, but then you would be making Jesus just another phrophet or philosopher or whatever, and then it wouldnt be anything more than just another religion/philosophy. It is your choice to believe that, and call yourself a Christian if you like. If you get another to join you, then you now have two in your church. But if you do believe that, then either your leader is a liar, or, you have to believe that 12 men conspired and lied about it, even to the point of death, which is not possible. It has been shown that human nature is such, that at the threat of death, only so many people can be involved in a plot before one gives in.
You do realize Peter was crucified upside down?
The crucifixion and resurection is what makes Christianity Unique.
Yes, the Romans and Jews are guilty of his death. It is a bitter/sweet situation. We can celebrate that he gave us everlasting life if we choose, but still have sorrow that He had to suffer so.
It was in Gods plan from the beginning, not too hard to figure that when he sent His Son into the world, the world would reject him, even unto death. Its pretty easy to see thats how humans would respond. Without that event being so predictable, I doubt God would have created people.
Jesus did have Thomas feel the wounds in his body did he not? Hence, "doubting Thomas".
Yea, Islam distorted the Bible pretty good, convenient how they claim only "certain" passages were written wrong.
Jesus dieing for our sins is comparable to a father dieing so his son could live. You would be sad for the father, and happy for the child. If the choice was made, say, in a criminal act by someone, then that person is still guilty.
Consider this, a man's son is dieing, He needs blood. He has an incompatable blood type from his dad. No blood is found for the boy. He is doomed. A criminal breaks in and shoots the man, he dies. During an autopsy, its discovered that actually, his blood type is the same as the boys, and it saves the boys life. We have reason to celebrate? We have reason to mourn? We still hold the criminal accountable? Are we angry at the criminal?
I have never understood the hatred for Jews over the crucifixion. I think its just an excuse.
As for finding a religion without supernatural beliefs, thats kinda an oxymoron. The virgin birth, resurection etc, are easy as pie for someone who created the whole universe.
Yea, the stories might be old, that doesnt invalidate them. The "theories" that people come up with, they present them as though they are fact. Odd, that in other areas, if we come up with a possiblity, we cant claim them as fact unless you present some evidence. Please provide some evidence on your theory.
