Early Life and Calling of Sts. Soter and Caius
Sts. Soter and Caius were two early popes of Rome who are commemorated together on April 22. Pope Soter (reigned c. 166-175) was known for his generosity in sending aid to persecuted Christians and imprisoned believers throughout the empire. Pope Caius (reigned c. 283-296) governed the Church during the persecution of Diocletian and was traditionally believed to be a relative of the emperor himself.
The vocation of Sts. Soter and Caius reminds us that holiness is not the exclusive domain of monks and nuns but the universal call of every baptized Christian. The Second Vatican Council's Dogmatic Constitution Lumen Gentium teaches that all the faithful are called to the fullness of Christian life and the perfection of charity — and Sts. Soter and Caius's life is a shining example of that universal call answered with total generosity.
