1 Corinthians 11:10-15

This [i.e., the order of creation] is the reason that the woman should have [a symbol of] authority on her [physical] head [i.e., hair or a shawl to indicate subjection to her husband], and because of the angels. [Note: This difficult phrase probably means that angels, who observe the activities of Christian assemblies, are pleased when they see things being done in their proper order].
