The statement that describes a way in which Christianity spread after Jesus’ death is "Peter and Paul traveled throughout the empire spreading the message of Jesus."
Before Jesus died on the Cross, he gathered his Apostles and told them that he won't be there for long. After his death, the Apostles followed Jesus' teachings and kept on spreading Christianity in other places. For instance, Peter and Paul kept on teaching the doctrine in Asia and other parts of Europe. The Apostles were the force that decided to spread the teachings despite the difficult circumstances. Apostle Paul was imprisoned and in jail, he wrote his famous "Letters."
