Many parents think children need to hear the word "no" frequent and often. This is a common attitude amongst American parents. Most American parents need an attitude adjustment on this front. The fact of the matter is that if you say "no" to your child enough times, and defend it in open court, you are abusing your child.
God's Law on child abuse is stated in Colossians 3:21 KJV:
Fathers, provoke not your children to anger, lest they be discouraged.
The Greek root word translated "provoke...to anger" is ερεθιζο (Latin: erethizo) and refers here to offenses or damages, namely the slightest of personal offense perceived by a child, including, but not limited to, the slightest of offensive touch or speech perceived by a child, stemming from entitlement. It is not enough to stop spanking and punishing your children - you need to ideally avoid the slightest of offense perceived by a child. One way to offend a child is to say "no" all of the time. Sometimes, saying "no" is necessary. However, if you defend your so-called "right" to say "no" all of the time, you are entitled as a parent, with any offense stemming from frequent use of the word "no" constituting child abuse when the offense stems from entitlement. Any time you cause a child to be upset, you are offending them. The idea is instead to apologize whenever a child is upset by the word "no", and try to avoid saying "no", or otherwise declining a request, whenever possible. This apology should usually come in the form of an informal apology, such as "I'm sorry, but I have to set X limit for Y reasons". However, you should never even use the word "no" if you are angry with your child, as losing your cool with your child alone is a form of entitlement. If you lose your cool with your child, a formal apology is necessary, such as "I apologize for losing my cool with you", with you then committing to not losing your cool with your children again. This commandment cross-references the Eighth and the Tenth Commandments, with the Apostle Paul here convicting a group of Greek Christian parents who brought into the church the pagan custom of patrias potestas, which is a Latin phrase roughly translating to "power to the parent", including the power of the parent to impose punitive sanctions on children, such as spanking or other forms of punishment. Paul, contrary to popular legend, was anti-spanking, and opposed any and all punitive parenting in his secular writings. Attachment parenting was banned under Roman law, but the Early Christians did it anyway, obeying God over men.
The word "no" in parenting is to be used rarely, meaning almost never. Under customary law in the Early Church, the word "no" was banned except in the narrowest of circumstances. The word "no" was reserved for when the petitioned request of the child was unsafe, unworkable, and/or immoral. Whenever you use the word "no" all of the time, you sever the secure attachment between parent and child.
Even in the case of declining a petitioned request, parents rarely gave a firm "no". Instead, parents used nicer-sounding words when declining a request coming from a child. These phrases include statements such as "that won't work", "that can't happen", or "that's not possible". If the child cannot accept the limit, apologize to your child to cushion the blow of a declined request.
The idea of anger being a motivator for parents to say "no" is alien to the biblical context. Any anger at a child then was seen as akin to a viper lashing out at a child. Instead, parents in the Early Church worried about their children, and set limits out of pure concern for the child. Mothers especially, in the Early Church, were prone to worrying all the time about their children.
The depraved and entitled parents who provoke their children to anger through punitive parenting will not inherit the Kingdom of God! Let them be cast forever into the lake of fire and burning sulfur, which is the second death prepared for Satan and his accomplices! Let them descend into the abyss which is the ever-burning Hell of fire and torment, suffering God's Wrath day and night forever and ever! Repent, for the Kingdom of Heaven is at hand!
