Ubi Arcano Dei Consilio §50

⁵⁰ Of your praiseworthy industry, We have had a quite recent proof on the occasion of the International Eucharistic Congress held in Rome and of the celebration of the Centenary of the Sacred Congregation of the Propagation of the Faith, when several hundred bishops from all sections of the globe were reunited with Us before the tomb of the Holy Apostles. That brotherly reunion, so solemn, because of the great number and high dignity of the bishops who were present, carried our thoughts to the possibility of another similar meeting of the whole episcopate here in the center of Catholic unity, and of the many effective results which might follow such a meeting toward the re-establishment of the social order after the terrible disorders through which we have just passed. The very proximity of the Holy Year fills Us with the solemn hope that this Our desire may be fully realized.
