A detailed representation of Galatians 2:8 from the Bible, with a figure symbolically representing the inspirational strength working within Apostles, as if heralding a call to circumcision and a separate entity embodying the might directed towards Gentiles. The image should be illustrated with meticulously crafted shading, style, and composition, as seen in the Gothic era. Also, the image should incorporate the aesthetics of stained-glass art, reminiscent of the narrative depictions present in medieval church windows.
