[8:15] 1 tn Grk “slavery again to fear.”
[8:15] 2 tn The Greek term υἱοθεσία (Juioqesia) was originally a legal technical term for adoption as a son with full rights of inheritance. BDAG 1024 s.v. notes, “a legal t.t. of ‘adoption’ of children, in our lit., i.e. in Paul, only in a transferred sense of a transcendent filial relationship between God and humans (with the legal aspect, not gender specificity, as major semantic component).”
