In Christian theology, the Supernatural order is, according to New Advent, defined as "the ensemble of effects exceeding the powers of the created universe and gratuitously produced by God for the purpose of raising the rational creature above its native sphere to a God-like life and destiny." The Modern Catholic Dictionary defines it as "[t]he sum total of heavenly destiny and all the divinely established means of reaching that destiny, which surpass the mere powers and capacities of human nature."
In Christian philosophy 
According to New Advent, "the philosophical possibility and the critical ascertainment of the supernatural order are the central point of Christian apologetics."
In Supernaturalism 
According to supernaturalism, a supernatural order is the original and fundamental source of all that exists. Accordingly, it is this supernatural order which defines the limits of what may be known.
