If parents would have their children blessed at church and at school, let them beware they give their children no corrupt examples at home by any carelessness, profaneness, or ungodliness. Otherwise, parents will do them more harm at home than both pastors and schoolmasters can do them good abroad. For the corrupt example of the one fighteth with the good instruction of the other, which is so much the more dangerous because that corrupt walking is armed with nature, and therefore more forcibly inclineth the affections of the children to that side.
Richard Greenham
