Robert Barron, bishop-elect of the Diocese of Winona-Rochester, celebrated the feast day of Sts. Peter and Paul, two of Jesus' apostles, with a simple tweet on Wednesday.

“Sts. Peter and Paul, pray for us!” the tweet said.

Sts. Peter and Paul share a feast day, June 29, the a report from the Catholic News Agency (CNA) said. 

“Both apostles share the same feast day, for these two were one; and even though they suffered on different days, they were as one,” St. Augustine of Hippo said of the joint celebration, quoted in the CNA report. “Peter went first, and Paul followed. And so we celebrate this day made holy for us by the apostles' blood. Let us embrace what they believed, their life, their labors, their sufferings, their preaching, and their confession of faith.” 

St. Peter was a fisherman when Jesus called him to be his disciple, Britannica said. He went on to be recognized as the leader of the 12 disciples and later became the first Catholic pope.

The Gospel of Matthew describes Jesus’ creation of the papacy. The recount said Jesus informed Peter, "And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”

Paul, once called Saul, was a Jew who persecuted Christians until one day, while he was traveling to Damascus, a bright light appeared before him and blinded him; the Rochester Bible Institute said. 

He heard a voice asking, "Saul, Saul, why do you persecute me?" The voice was identified as coming from Jesus. Saul was taken to Damascus where, still blind, he did not eat or drink for three days, the Scripture said.

Jesus appeared in a vision to a disciple named Ananias and instructed him to go to Saul, the Scripture said. Ananias was frightened because of Saul's reputation, but he obeyed Jesus. Ananias told Saul that he had been sent by Jesus to restore his vision so that Saul could be filled with the Holy Spirit. Ananias laid his hands on Saul, and scales fell from Saul's eyes, restoring his vision. Saul was converted, and he was baptized and changed his name to Paul.
