Hebrews 10:29
"has regarded as unclean the blood of the covenant by which he was sanctified"
Hebrews 10: KJV
29 "Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and
hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?"
There are people who believe the doctrine of the Atonement of the LORD Jesus Christ is an unholy thing,, Some people think it is foolishness.. but for some others who are religious it is considered a stumblingblock / stone ( unholy )
1 Corinthians 1: KJV
23 "But
we preach Christ crucified, unto the Jews a
stumblingblock, and unto the Greeks
foolishness; {24} But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God."
Those who mock the Atonement of Jesus are trampling upon His Blood and those who call it an evil doctrine are doing likewise..
