“Thus David the Prophet says: ‘My God, His mercy shall go before me.’ (Psal. LVIII) and again: ‘my mercy shall be with him’ (Psal. LXXXVIII) and in another place: ‘And thy mercy will follow me’ (Psal. XXII). Similarly Bl. Paul also says: ‘Or who hath first given to him, and recompense shall be made him? For of him, and by him, and in him, are all things’.” Pope Boniface II, Epistle ad Caesarian Arelatensem
