Except that not all christains believe those "truths".<quoted text>
...When I say "core truths" I am speaking of the very basic concepts that all Christians believe:...
Jesus was born of a virgin (How doesn't matter)
Nope. Not a core belief but the Muslims agree with you.
Jesus was baptized by His cousin
It is not agreed that John and Jesus were cousins. It is not supported by the NT.
Jesus had a 3 year ministry
Nope. There is disagreement on the time between His baptism and Death.
Jesus was killed by Roman crucifixion
Nope. Most Christians claim He was executed by the Jews. It is also unclear whether he was crucified or hung and also whether he died or survived.
Jesus was resurrected from the dead (again, how doesn't matter)
Nope. The ressurection is not required for belief in a few sects.
Jesus ascended into Heaven (once again, how doesn't matter)
Well, most believe that everyone goes to Heaven so Jesus is no different.
Jesus will return (go ahead, guess what my preemptive comment is)
Wrong again. There are preterist that do not believe in the "end times". Hiwever it is a belief in Judaisn and Islam.
What you are trying to do is claim that your bliefs are the same as 1.5 billion other people. That is 100% untrue.
"Only real Christians" dodge in 3... 2... 1....
