5 Although a great deal of its work has been completed, there is still much for you to do, Venerable Brothers, in the next session, which will also be the last. The period which follows that session will be equally important. At that time the Council's decisions will have to be implemented. Priests and people will be called upon to combine their efforts so that the seeds sown during the Council may bear tangible, salutary fruit. And so, to obtain the necessary enlightenment and divine blessings for completing this great volume of work, We place Our hope in her whom We gladly proclaimed Mother of the Church at the close of the last session. From the very start of the Council she has given us her loving help, and she will surely stay with us until the task is finished.
