The feast is found only in the special calendar of some dioceses and religious orders, and is celebrated with proper Mass and Office either on the third Sunday of July or on 23 October.
To avert this scourge the Venetian Senate vowed to erect a splendid temple to the Redeemer of mankind, and to offer therein each year on the third Sunday of July public and solemn services of thanksgiving.
By concession of Pope Benedict XIV, dated 8 March, 1749, the Congregation of the Most Holy Redeemer solemnizes this feast as a double of the first class with an octave on the third Sunday of July.
The same congregation also keeps the feast as a greater double on 23 October and 25 February, and has, besides, the privilege of reciting once a month the votive office of the Most Holy Redeemer.
In Rome also Pope Pius VIII introduced the feast and by a Decree of 8 May, 1830, the Sacred Congregation of Rites assigned it to 23 October.
