St. Praxedes
A virgin saint from the earliest Christian times who placed her goods and her services at the disposal of the Church! The life of this saint, like that of most other early Christian saints, remains concealed in the obscurities of legend.

Praxedes, it is said, was the sister of St. Pudentiana; she was devoted to the practice of works of mercy, particularly towards martyrs, during the reign of Emperor Antoninus (138-161). "Some she kept in hiding in her house, others she encouraged to profess the faith heroically, and the dead she buried. To those languishing in prison she brought needed assistance. When she no longer could endure the sight of the cruel oppression to which Christians were subjected, she implored the Lord to take her from this vale of tears if such were His holy will. It was. On July 21 the Lord called and gave her heaven as the reward for her piety and love of neighbor. Her body was placed in the catacomb of Priscilla in the tomb of her father Pudens and her sister Pudentiana".

St. Prassede was also the sister of St. Novatus and of St. Timothy, who was a disciple of St. Paul. Sts Peter and Paul would visit their home, which is today a beautiful church, just 2 stone-throws from the Basilica of St Mary Major, in via S. Prassede.

Pudens, her father, is referred to in 2 Timothy 4:21. (Make haste to come before winter. Eubulus and Pudens, and Linus and Claudia, and all the brethren, salute thee.)

When at last the sight of the butchery of Christians was more than she could bear, and after many years of burying mutilated Christians, visiting the imprisoned, and seeing those she loved suffer, she implored God that, if it were expedient for her to die, He would release her from such suffering.  And so she was called to receive the crown of martyrdom herself.  

Pastor the Priest laid her body in the grave of her father and her sister Pudentiana, which was in the Priscilla catacombs, upon the Salarian Way.

When Pope Paschal I (817-824) rebuilt the church as the present Santa Prassede he translated to it the bones of Sts. Praxedes, Pudens, Potentiana, and other martyrs.

This church contains a large portion of the Pillar at which Our Lord Jesus was scourged,  and the bones of many martyrs, and the most wonderful mosaics.

Don't miss it if you go to Rome. It is my favorite Church.

Santa Prassede, ora pro nobis!
