Paragraph 7. THE FALL

406
The
Church’s teaching on the transmission of original sin was articulated more
precisely in the fifth century, especially under the impulse of St. Augustine’s
reflections against Pelagianism, and in the sixteenth century, in opposition to
the Protestant Reformation. Pelagius held that man could, by the natural power
of free will and without the necessary help of God’s grace, lead a morally good
life; he thus reduced the influence of Adam’s fault to bad example. the first
Protestant reformers, on the contrary, taught that original sin has radically
perverted man and destroyed his freedom; they identified the sin inherited by each
man with the tendency to evil (concupiscentia), which would be insurmountable.
the Church pronounced on the meaning of the data of Revelation on original sin
especially at the second Council of Orange (529)²⁹⁶ and at the Council
of Trent (1546).²⁹⁷
