Not the least of which is this strong passage in Sirach:
{3:2} Sons, listen to the judgment of your father, and act accordingly, so that you may be saved.
{3:3} For God has honored the father in the sons, and, when seeking the judgment of the mother, he has confirmed it in the children.
{3:4} He who loves God will plead with him on behalf of sins, and will keep himself away from sin, and will be heeded in the prayers of his days.
{3:5} And, like one who stores up treasure, so also is he who honors his mother.
{3:6} He who honors his father will find happiness in his own children, and he will be heeded in the day of his prayer.
{3:7} He who honors his father will live a long life. And he who obeys his father will be a refreshment to his mother.
{3:8} He who fears the Lord honors his parents, and he will serve them as masters, for it is they who conceived him.
{3:9} In word and deed, and in all things, honor your father with patience,
{3:10} so that a blessing may come to you from him, and so that his blessing may remain to the very end.
{3:11} The blessing of the father strengthens the houses of the sons; but the curse of the mother uproots even its foundation.
{3:12} Do not boast in the disgrace of your father; for his shame is not your glory.
{3:13} For the glory of a man is from the honor of his father, and a father without honor is a discredit to the son.
{3:14} Son, support your father in his old age, and do not grieve him in his life.
{3:15} And if his mind should fail, show kindness; and do not spurn him when you are in your strength. For almsgiving to the father will never be forgotten.
{3:16} For even in return for the sin of the mother, good will be repaid to you.
{3:17} And you will be built up in justice, and you will be remembered in the day of tribulation. And your sins will dissolve like ice in warm weather.
{3:18} What an evil form has he who forsakes his father! And whoever exasperates his mother is accursed by God.
