But so the corollary of the your claim is that the Christ did other things, in addition to 'only' be 'crucified'.
Paul wrote about a minimal Jesus (but also, for Paul, pre/post-existent as a heavenly deity) who, from "Israelites, ... whose [are] the fathers, and of whom [is] the Christ, according to the flesh ..." (Ro9:4-5 YLT) and
"come of a woman, come under law" (Gal4:4 YLT) (as a descendant of (allegedly) Abraham (Gal3:16), Jesse (Ro15:12) & David (Ro1:3)), "found in appearance as a man" (Php2:8) "in the likeness of sinful flesh" (Ro8:3), "the one man, Jesus Christ" (Ro5:15) (who had brothers (1Co9:5), one of them called "James", whom Paul met (Gal1:19)),
"humbled himself" (Php2:8) in "poverty" (2Co8:9) as "servant of the Jews" (Ro15:8) and "was crucified in weakness" (2Co13:4) in "Zion" (Ro9:31-33 & Ro11:26-27) (
