Ethereal + 100% FR vs. Flaming weapon bless

[PsiSoldier]

Ok if a Flaming weapons bless counts as a Magic weapon but only the Fire damage portion of the attack counts as magic then if a unit was Ethereal And also had 100% Fire resist would the Flaming weapons actually hit the unit all the time or would the Ethereal portion work so that he was only hit 25% of the time since the FR would presumably counter the Flaming weapons???
