Catena Aurea on Matthew 6:10: Augustine of Hippo

This is not so said as though God did not now reign on earth, or had not reigned over it always. “Come,” must therefore be taken for “be manifested to men.” For none shall then be ignorant of His kingdom, when His Only-begotten not in understanding only, but in visible shape shall come to judge the quick and dead. This day of judgment the Lord teaches shall then come, when the Gospel shall have been preached to all nations; which thing pertains to the hallowing of God’s name.
