idolatry:

Second Commandment:  no diversion or dilution of God's leadership/authority to subset intermediaries, nor imprecision of responsibility/guilt in the carrying out of  God's Will & repair of the damages of sin, such as via raising up of alternative goals/idols -- like family/race/class/nation/patriotism/language/religion/fraternity/culture/etc. -- as excuses to fully or partially set-aside God's WILL; God's commands become secondary to the human/societal preoccupation of the moment.
