Advent Reflections Day 2

We preach not one advent only of Christ, but a second also, far more glorious than the former. For the former gave a view of His patience, but the latter brings with it the crown of a divine kingdom… In His former advent, He was wrapped in swaddling clothes in the manger; in His second, He covers Himself with light as with a garment. In His first coming, He endured the Cross, despising shame; in His second, He comes attended by a host of Angels, receiving glory.

…Our Lord Jesus Christ, then, comes from heaven; and He comes with glory at the end of this world, on the last day. For of this world, there is to be an end, and this created world is to be re-made anew.

Cyril of Jerusalem, Catechetical Lecture 15;
