In worship, silence is far more that the absence of sound. Silence constitutes a vital part of the divine-human dialogue. In silence, worshipers can experience interchanges with God that will not be known where silence does not prevail.
The quiet hour of prayer is one of the most favourable opportunities he has in which to speak to us seriously. In quietude and solitude before the face of God, our souls can hear better than at any other time.
Silence promotes the presence of God, prevents many harsh and proud words, and suppresses many dangers in the way of ridiculing or harshly udging our neighbours…If you are faithful on keeping silence when it is not necessary to speak, God will preserve you from evil when it is right for you to talk.
