After receiving the power of the Holy Spirit which had been promised to them, so that they could work miracles and proclaim the truth, they first bore witness to their faith in Jesus Christ and established churches throughout Judea. They then went out into the whole world and proclaimed to the nations the same doctrinal faith. They set up churches in every city. Other churches received from them a living transplant of faith and the seed of doctrine, and through this daily process of transplanting they became churches. They therefore qualify as apostolic churches by being the offspring of churches that are apostolic. Every family has to be traced back to its origins. That is why we can say that all these great churches constitute that one original Church of the apostles; for it is from them that they all come.
