The Diocese of Pensacola-Tallahassee marked the shared feast day of Sts. Peter and Paul, two of Jesus' Apostles who used their ministry talents to establish the See of Rome, on Wednesday.

“Today is the Solemnity of Sts. Peter and Paul, Apostles,” the diocese posted on Facebook. "Together, they are the founders of the See of Rome, through their preaching, ministry and martyrdom.”

Sts. Peter and Paul share a feast day because they are seen as a unit, Catholic News Agency says, citing this quote: “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. “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 working as a fisherman when Jesus called him to be his disciple, according to Britannica. Peter is recognized as the leader of the 12 disciples and as the first Catholic Pope.

“Jesus gave him the name Cephas, which means rock, because he was to become the rock upon which Christ would build His Church,” the diocese said in its post. “Peter was a bold follower, the first to recognize Jesus as ‘the Messiah, the Son of the living God.’”

The Gospel of Matthew describes Jesus' guidance for creating the papacy, with Jesus saying to 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.”

Peter was martyred in the year 64, crucified upside-down at his own request, as he claimed to be unworthy to die the same way his Lord died, the diocese said.

Paul, formerly called Saul, was a Jew who persecuted Christians until one day, while on the road to Damascus, he was blinded by a bright light, the Rochester Bible Institute recounts.

One day, he heard a voice say unto him: "Saul, Saul, why do you persecute me?" The voice identified himself as belonging to Jesus. Saul was taken to Damascus where, still blind, he did not eat or drink for three days, the institute says.

Jesus appeared in a vision to a disciple named Ananias. He directed Ananias to go to Saul, the story goes. Ananias was hesitant because of Saul's reputation toward Christians, but he obeyed Jesus. Ananias visited Saul, telling Saul he had been sent by Jesus in order to restore his vision so he could be filled with the Holy Spirit. Ananias laid his hands on Saul in a healing manner, and scales fell from Saul's eyes, allowing him to see once again. Saul was thus converted, and when he was baptized, he changed his name to Paul.

“He was imprisoned and beheaded in the year 67,” the diocese added. “Sts. Peter and Paul, thank you for your leadership and sacrifice for the early Church. Please, pray for us!”
