The faithful, whenever they recite a third part of the Rosary with devotion, may gain: An indulgence of 5 years (S. P. Ap. March 18, 1932).
If they recite a third part of the Rosary in company with others, whether in public or in private, they may gain: An indulgence of 10 years, once a day; a plenary indulgence on the last Sunday of each month, with the addition of confession, Communion and a visit to a church or public oratory, if they perform such a recitation at least three times in any of the preceding weeks. If however, they recite this together in a family group, besides the partial indulgence of 10 years, they are granted: A plenary indulgence twice a month, if they perform this recitation daily for a month, go to confession, receive Holy Communion, and visit some chureh or public oratory (S.P. Ap., Mar. 18, 1932 and July 26, 1946).
Those who piously recite a third part of the Rosary in the presence of the Blessed Sacrament publicly exposed or even reserved in the tabernacle, as often as they do this, may gain: A plenary indulgence, on condition of confession and Communion (Ap., Brief, Sept. 4, 1927).
