He who is anxious to attain a true understanding of holy Scripture, will discover the spiritual truths which are spoken by it to those who are called "spiritual," by comparing the meaning of what is addressed to those of weaker mind with what is announced to such as are of acuter understanding, both meanings being frequently found in the same passage by him who is capable of comprehending it.
OrigenThose who believe the Author of Nature to be also the Author of Scripture must expect to find in Scripture the same sorts of difficulties that they find in Nature.
OrigenWhen a house is being built which is to be made as strong as possible, the building takes place in fine weather and in calm, so that nothing may hinder the structure from acquiring the needed solidity.
OrigenIt can be shown that an incorporeal and reasonable being has life in itself independently of the body... then it is beyond a doubt bodies are only of secondary importance and arise from time to time to meet the varying conditions of reasonable creatures. Those who require bodies are clothed with them, and contrariwise, when fallen souls have lifted themselves up to better things their bodies are once more annihilated. They are ever vanishing and ever reappearing.
OrigenThe soul has neither beginning nor end [They] come into this world strengthened by the victories or weakened by the defeats of their previous lives
OrigenEvery soul that is born into flesh is soiled by the filth of wickedness and sin. . . . In the Church, baptism is given for the remission of sins, and, according to the usage of the Church, baptism is given even to infants. If there were nothing in infants which required the remission of sins and nothing in them pertinent to forgiveness, the grace of baptism would seem superfluous
Origen
