Isaiah 1:11
The context
Isaiah's opening oracle summons heaven and earth as witnesses against a people who have rebelled. The indictment moves from covenant breach to the state of the worship: assemblies, feasts, and offerings are named as burdens. Verse 11 gives the divine refusal in the first person, with verse 15 adding that the hands raised in prayer are full of blood.
What it establishes
It establishes that worship divorced from justice is rejected, and that the rejection is stated in the strongest terms. The prophet does not contrast temple worship with a spiritual alternative; he contrasts worship as currently practiced with the justice it was supposed to accompany.
What it does not establish
It does not establish that God rejected the temple or the sacrifices as such. The same book envisions the nations streaming to Zion and the offerings of Israel accepted. The oracle is a call to wash and learn to do good, not a decree that ritual is finished.
