A few quotes from the Rabbi on 'Traditions of the Fathers'
in which his teaching warns bridegrooms not to spend more on their weddings than they can afford
"Be careful about governance" – even beyond what is permitted. You may consume kosher meat and permitted wine and the like, but even if they are permitted, it is forbidden to be wicked within the limits of the Torah's law, as our renowned Sages, of blessed memory say. This is even more the case when great expense is involved…from which comes this warning to some young men who spend much more than they can afford on their weddings, selling their clothing and furnishings to revel in delicacies and wine, as though they were of royal descent. "Eat, friends, and drink; drink deep, loving companions" while they, having neither friends nor companions, scatter monies without measure. Some will remain penniless after the wedding, with no funds left for the commerce or craft required to respectably earn their living. One to whom God has granted common sense will "conduct his affairs with equity", in keeping with his means and no more, for his friends and companions, having eaten and drunk with him on his wedding day, will be silent in his hour of distress and leave him on his own when he is tending to his troubles.
