What does Leviticus 22:21 mean?

No descendant of Aaron with any of these conditions can come near to offer food to God. If he has a physical defect, he can't approach the altar to present the offerings. Leviticus 22:21 - Modern Text Bible

(Even if someone is from the priestly family, physical defects disqualify him from making offerings. This is about ritual standards, not about a person's value or relationship with God.)
