"[E]xcommunication is the rod of a pious mother over a bad son, whom she does not therefore regard as not a son because she whips him, but chastises him severely that he may reform and not cease to be a son altogether."
- Francis Turretin, Institutes of Elenctic Theology, Fifteenth Topic, Question XVI, Section XL (page 613 of Volume 2, in Giger's translation as recently published)
Original Latin: Excommunicatio est flagellum piae Matris in pravum filium, quem non quia flagellat, ideo habet pro non filia, sed castigat graviter, ut emendet, ne fiat omnino non filius.
We, in this modern age of moral decay, should not be surprised to see that both church and family discipline have been corrupted similarly, such that in churches where severe discipline for the restoration of children is not (or rarely) practiced, severe discipline for the restoration of congregants is not (or rarely) practiced.
The parallel remains, though the Refomers would condemn our generations for failing to heed the Word of God as it pertains to discipline, both ecclesiastical and parental.
