Their debtors (ofeiletai autwn). Objective genitive: the Gentiles are debtors to the Jews. See the word ofeilethv in Romans 1:14; Romans 8:12.
For if (ei gar). Condition of the first class, assumed as true, first aorist active indicative (ekoinwnhsan, from koinwnew, to share) with associative instrumental case (pneumatikoiv, spiritual things).
To minister unto (leitourghsai, first aorist active infinitive of leitourgew with dative case autoiv, to them), but here certainly with no "sacerdotal" functions (cf. verse Romans 15:16).
In carnal things (en toiv sarkikoiv). Things which belong to the natural life of the flesh (sarc), not the sinful aspects of the flesh at all.
