When Jesus was executed by the Italians (Hi Sidd) Tiberius was Emperor. Jesus was clearly executed under the authority of the Emperor as crucifixion was an exclusively Roman form of execution and at that time everything official Romans did, they did in the name of the Emperor. Tiberus, was not only the Emporer but the Pontifex Maximus:

So Jesus was killed under the authority of the Pontifex Maximus of Rome. And now most of the Christian world looks to Jesus' heir on earth as the Pontifex Maximus in Rome (the Pope).
So Christians worship a God that is Jewish, and accept as his intercessor on earth, a person that holds the same office as the man that was responsible for executing that very God.
