Derived from the privative alpha and spilos ('spot, stain'), aspilos describes what is free from any blemish or moral stain. The word operates across both ethical and cultic registers in the NT. Peter applies it to Christ as a lamb 'without spot or blemish' (1 Pet 1:19), drawing on sacrificial imagery. James defines 'pure religion' as keeping oneself 'unstained' from the world (Jas 1:27). Paul urges Timothy to keep the commandment 'spotless' until Christ's appearing (1 Tim 6:14), and Peter exhorts believers to be found 'without spot' at the Lord's return (2 Pet 3:14). German 'fleckenlos' and Spanish 'sin-mancha' both transparently render the privative sense of being without stain.
