In Christian theology, actual sins are individual, concrete evil actions, performed in violation of the Law of God as recorded in the Bible. These are seen as the result of Original Sin, or the sinful nature possessed by all human beings.
One is a sin per se, "of itself;" another, per accidens, "accidentally." (1.) A sin per se is every external or internal action which is prohibited by the law, or every neglect of an action commanded by the law.
Sin is also divided into venial and mortal: but this distribution is not deduced from the nature of sin itself, but accidentally from the gracious estimation of God.
The effect of actualsins are all the calamities and miseries of the present life, then death temporal, and afterwards death eternal.
