Without Jesus there would be no Church. Keep in mind Paul was a Roman, chosen by God, to bring Jesus' Church into Rome. Meanwhile, others were bringing the Church to Africa, India, Syria and other parts of the world. Peter, the steward of the Church after Christ ascended, was crucified in Rome and his body buried on the southern slope of the Vatican hill.
At the time, Roman ideology and literature metaphorically described their empire reaching to the ends of the earth. Note Jesus used this metaphor instructing his disciples to proclaim his Gospel to the ends of the earth--in other words--all over the Roman empire.
