Blemish

imperfection or bodily deformity excluding men from the
priesthood, and rendering animals unfit to be offered in
sacrifice (Lev. 21:17-23; 22:19-25). The Christian church, as
justified in Christ, is "without blemish" (Eph. 5:27). Christ
offered himself a sacrifice "without blemish," acceptable to God
(1 Pet. 1:19).
