Good and necessary counsel to elders , even today...
"Do not make unnecessary rules. If elders make unnecessary rules, they will create a burden for others. Brother Juraj Kaminský recalled what took place during the ban in former Czechoslovakia: “After the responsible brothers and many elders were arrested, some of those taking the lead in congregations and circuits began prescribing rules of conduct for the publishers, making lists of dos and don’ts.” Jehovah has not given us authority to make personal decisions for others. Someone who makes needless rules is not protecting his brother’s safety—he is trying to become the master of his brother’s faith."
