Jesus set up an impossible paradox when he explained that the two great commandments are to love God and to love one’s neighbor (though he was not the first to summarize the Law in such a way). The problem is that one simply cannot do both, as Jesus himself elsewhere noted that one cannot serve two masters.
King Benjamin saw the impossible tension between these two contradictory commandments and attempted to resolve it by collapsing them into one single ethical imperative. He said: “when ye are the in the service of your fellow beings ye are only in the service of your God” (Mos 2:17). The attempt to equate the love of God and the love of neighbor as simply one ethical imperative elides the problem of having two competing duties. The problem (or promise, depending on your perspective) with such a position is that the duty to love God cannot possibly come into conflict with the duty to love one’s neighbor.
