hello Eugene, dirtfarmer here There is no mandate to the seven churches in Revelation for animal sacrifices, but there are mandates for those in those seven churches to be overcomers. Chapter 2 v10 be faithful unto the end to receive crown of life v11 he that overcometh will not be hurt of the second death. v17 to him that overcometh will eat hidden manna and receive a white stone with a new name. v26 to him that overcometh power over the nations & will rule with a rod of iron Chapter 3 v5 he that overcometh shall be clothed in white raiment & name will not be blotted out of the book of life v10 kept from temptation that will come upon all the earth (tribulation?) v12 he that overcometh will be made a pillar in the temple of God & shall go out no more v 21 he that overcometh will be granted to seat with Christ in his throne. Do these things that are granted to the seven churches sound as if it is the body of Christ or does it seems like things that will happen during the earthly kingdom that is promised to Israel?
