He prohibited us from offering the sacrifices of gentiles when they are animals with blemishes; and we should not say, "Since he is a gentile, we will offer an animal with a blemish for his sake." And that is His, may He be exalted, saying, "And from the hand of a gentile, you may not offer" (Leviticus 22:25). And one who transgressed and offered [it] is lashed. (See Parashat Emor; Mishneh Torah, Things Forbidden on the Altar 1.)
