Reformed theology studies the logical order of God's decree to ordain the fall of man in relation to his decree to save some sinners through election and condemn others through reprobation. Several opposing positions have been proposed, all of which have names with the Latin root lapsus (meaning fall), and the word stem (a type of root) -lapsarianism.
Supralapsarianism and infralapsarianism assert that election and reprobation respectively preceded and succeeded the Fall logically, not temporally.
