Pope St. Pius X confirms the practice of the Fourth Lateran Council in QUAM SINGULARI, August 8, 1910: “This new practice, already accepted by certain local councils, was solemnly confirmed by the Fourth Council of the Lateran, in 1215, which promulgated its celebrated Canon XXI, whereby sacramental Confession and Holy Communion were made obligatory on the faithful after they had attained the use of reason, in these words: ‘All the faithful of both sexes shall, after reaching the years of discretion, make private confession of all their sins to their own priest at least once a year, and shall, according to their capacity, perform the enjoined penance; they shall also devoutly receive the Sacrament of Holy Eucharist at least at Easter time unless on the advice of their own priest, for some reasonable cause, it be deemed well to abstain for a while.’”
