Omnibenevolence (from Latin omni- meaning "all", and benevolent, meaning "good") is defined by the Oxford English Dictionary as "unlimited or infinite ". Some philosophers have argued that it is impossible, or at least improbable, for a deity to exhibit such property alongside omniscience and omnipotence as a result of the problem of evil. However, some philosophers, such as Alvin Plantinga, argue the plausibility of co-existence. The word is primarily used as a technical term within academic literature on the philosophy of religion, mainly in context of the problem of evil and theodical responses to such. Although even in said contexts the phrases "perfect goodness" or "moral perfection" are often preferred because of the difficulties in defining what exactly constitutes 'infinite benevolence'.
