Pope St Callixtus I

Pope Callixtus I was the first of three popes to choose the name Callixtus. He was the 16th pope of the Church and one of the early men martyred for their beliefs and positions.

Having spent his early years as a slave, he had a deep commitment to helping the poor. The life and death of Pope Callixtus I are some of the topics covered in this article.

Early Life

Born circa 155 AD, Callixtus was known as Kallistos until he became the pope. Though Greek by birth, he was born and raised in Rome and spent his whole life living in the Roman Empire.

Callixtus was a slave and belonged to a man named Carpophorus. His master collected funds from other Christians in the area to help young children and widows in need.

He gave the funds to Callixtus and asked him to deliver the money. Callixtus lost the money and escaped. When he was captured, the man attempted to run away but was captured a second time and sent back to his master.

Investors arranged his release in the hopes of getting some money back, but he was arrested again after fighting with Jews in a synagogue, presumably over a financial dispute. Persecution of Christians may have also contributed to his arrest. At this point he was sent to a forced labor mine at Sardinia, where he may have acted as a confessor.

He was freed by Pope Victor I with the help of the Roman Emperor’s mistress, Marcia, in an effort to free detained Christians, and he received a small allowance from the Pope. Callixtus then moved to Anzio.

Before His Papacy

In the hopes that Callixtus would repay the money he lost, his master let him go free. He was caught trying to force Jewish people in a local synagogue to repay their debts by force. This led to him being arrested and sent to work in the mines.

He became so sick in the mines that he was sent to Anzio to recover. Pope Victor believed that he was a good man who made some bad choices and gave him a pension for support. It was during this time that Callixtus turned to the Church and became a deacon.


As the 16th pope, Callixtus established policies that allowed heretics and others who spoke out against the Church to return. He converted some and absolved others of their sins. The pope believed that even those who murdered others, used early forms of birth control and indulged in other major sins were worthy of the Church. This led to Hippolytus rising as the antipope and converting followers to his side who did not agree with the pope.

Pope St. Callixtus I’s time as Pope was very short due to his early death in 222. Although he had many controversial policies, he had already started putting them in motion during Pope Zephyrinus’s reign, so he mostly continued the work he had previously done.


Callixtus practiced in the Basilica di Santa Maria and was martyred there in either 222 or 223. A popular legend from the time claimed that opponents attacked him in the church and threw his body in a well, leaving him to die there. Though modern historians doubt this happened, the church still has the remains of an ancient well on the property.

The legend also claims that Saint Asterius of Rome traveled to the church in the darkness of night and recovered the pope’s body, which he then had moved to the Cemetery of Saint Calepodius. For his actions, one of the pope’s opponents had Asterius arrested and thrown from a bridge.

During the 9th century, the relics of Pope Callixtus were set to his former church in Santa Maria.

Conflict with Saint Hippolytus

Saint Hippolytus’s writings contain most of the information that is currently known about Pope St. Callixtus I. He was one of Callixtus’s greatest rivals due to theological disputes. Hippolytus believed that only the Son was incarnated as Jesus, Callixtus supported the belief that both the Father and the Son were incarnated. Callixtus also had a big influence on Pope Zephyrinus, and Hippolytus felt that Callixtus prevented Pope Zephyrinus from supporting Hippolytus’s views.

Once he became Pope, Pope St. Callixtus I also had very lenient policies on who could be pardoned for their sins. He pardoned people for previously unforgivable sins such as adultery and murder once they repented. He even allowed these people to receive Communion after their penance. Bishops benefited from his lenient policies because he didn’t remove them from office for committing mortal sins if they repented.

He even pardoned former heretics and accepted unrepentant people from other sects of Christianity and allowed them to take Communion. Pope St. Callixtus I’s lenient policies extended to marriage laws as well. He allowed high-born women to marry commoners and slaves, even though it was against Roman law.

He also allowed lower members of the clergy such as parish priests to get married and ordained clergy members who had been married multiple times.

Because of Pope St. Callixtus I’s policies and views, Saint Hippolytus considered him a heretic.

Saint Hippolytus refused to acknowledge his rival as the Pope, so he gathered his own followers and created a schism in the Church. By creating this split, he became known as the first antipope.
