In this way, the research aimsto study the biblical text following the academic criteria recognized for analyzes of this character, to understand the elements that guide the theological meaning of Paul s use of diferente paradigmatic figures, centered on the idea of filiation, as an integral part of a great argument rhetorical, as a strategy of dialogue, defense and rescue of the Galatian community, threatened byindividuals who sought to contradict the apostle s preaching.
