Paul begins his letter by establishing his credentials as an apostle, a messenger chosen not by human decision or authority but by Jesus Christ and God the Father. This distinction is crucial as it underscores the divine origin of his mission and the message he carries. By stating that his apostleship is not from men, Paul emphasizes that his teachings are not influenced by human traditions or opinions but are rooted in the authority of Christ himself.
Furthermore, Paul mentions God the Father, who raised Jesus from the dead, highlighting the central Christian belief in the resurrection. This reference serves to remind the Galatians of the transformative power of the resurrection, which is the foundation of the Christian faith. By connecting his apostleship to this pivotal event, Paul reassures the Galatians of the authenticity and divine backing of his message. This introduction is not just a formality but a profound declaration of the source and legitimacy of his teachings, setting a tone of authority and divine purpose for the rest of the letter.
