From the Sermons of St Augustine, Bishop of Hippo. 2nd 07i the Ascension.
Dearly beloved brethren, our Saviour is gone up from us into heaven, but let us not be troubled on earth. Let only our heart be there with Him, and we shall have peace here. Let us in heart thither ascend with Christ in the meanwhile, and when that glad day which He hath promised cometh, our body will follow. But we must know, my brethren, that there are some things that cannot ascend with Christ: pride cannot, nor covetousness, nor brutishness; no one of our diseases can ascend thither where our Healer is. And, therefore, if we would follow our Healer, we must needs leave our diseases and sins behind us. All such things tie us down, as it were, with bands, and hamper us in the meshes of a net of sins but, with God's help, we will say with the Psalmist "Let us break their bands asunder”, that we may be able honestly to say to the Lord "Thou hast loosed my bonds I will offer to thee the sacrifice of thanksgiving".
