SUMMARY: Apparently, shedding blood is something that the church has been involved with from the first martyr, Abel, who was killed by his brother Cain. These pointed spiritually to the Elect who would be killed in tribulation. Cleansing the land seems to be the language of judgment as God allowed the church to destroy itself at the revelation of Christ.
