Summary of the biblical argument: blood transfusions are not eating blood; even if eating blood were prohibited, transfusions would be exempt; in Christ there is no food-purity prohibition at all; and even if there were, saving life overrides it.

The argument proceeds in four descending layers: (1) Blood transfusions are not eating — the dietary prohibition simply doesn't apply. (2) Even if it did apply, Orthodox Jews who take the law most seriously permit transfusions. (3) In Christ, food law prohibitions are abrogated (1 Cor 8:8; Rom 14:14; Matt 15:10-11; Col 2:16-22). (4) Even if a prohibition somehow applied, Jesus' greater-good principle (Luke 14; Luke 6) would make life-saving an exception.
