Orientalis Ecclesiae §41

⁴¹ To seminarists and to pupils of other colleges We specially commend the observance of the 'Day for the East'; on that day let prayers more than usually fervent be made to the Divine Shepherd of the whole Church, and let the hearts of the young be stimulated to a burning zeal for the achievement of this holy unity. Finally, let all, alike those who are in Sacred Orders and those who, as members of Catholic Action and other associations, are co-operating with the hierarchy of the Church, perseveringly direct their prayers, their writings, their discourses, to promoting this desired union of all Easterns with the common Father.
