In an age of division, one thing that pleases God the most is to see his children pray with a united voice.
This is something best described by St. Cyprian in a treatise on the Lord's Prayer.
Not only did God desire us to pray with one voice, he has shown that this is one of the most fruitful types of prayer.
It is an important lesson, showing us that God greatly desires us to be unified in prayer, all praying together in one family.
