Christian orthodoxy 101. No problem there. But it was man Jesus who suffered and died on the cross; not God. Christian orthodoxy 102.
Simple - just show me where God speaks out against ‘human’ sacrifice, and then also show me where He is required to follow all of His own mandates.
Everything in the Bible He told us so that:
a) we could see the true conditions of sin in our lives and
b) to make our lives better whether here and now or best of all in the after-life.
Hey, at least stop oblitering and revising historical Christianity as depicted in the New Testament and reinforced in the early church fathers' writings.
Those writings don't compartmentalize Jesus as you've just done...BOTH man...and God.
If YOU personally want to separate who Jesus is, that's one thing. To superimpose your view over that of the early church fathers and the NT and then call that "Christian orthodoxy," you have overblown hubris to do that.
