C.S. Lewis on Sin as Sacrilege
Every sin is the distortion of an energy breathed into us—an energy which, if not thus distorted, would have blossomed into one of those holy acts whereof ‘God did it’ and ‘I did it’ are both true descriptions. We poison the wine as He decants it into us; murder a melody He would play with us as the instrument. We caricature the self-portrait He would paint. Hence all sin, whatever else it is, is sacrilege.
— C. S. Lewis, Letters to Malcolm
