Final answer:
St. Nicholas gave money to three poor sisters according to legend so they could afford dowries and avoid destitution. This charitable act is a cornerstone of the spirit of giving that characterizes the modern-day Santa Claus tradition, teaching the value of generosity.
Step-by-step explanation:
According to the legend of Saint Nicholas, St Nicholas gave money to three poor sisters to save them from a life of destitution. This act of generosity is rooted in the moral imperative of caring for those less fortunate and exemplifies the spirit of giving without expecting anything in return. The sisters did not have a dowry, which in their time was necessary for marriage. Without this, they were at risk of turning to prostitution. Saint Nicholas's gift to them is considered not just an act of charity, but also one that preserved their dignity and provided them with new opportunities in life. This story has been passed down through the ages and has influenced the modern-day figure of Santa Claus, embodying the joy and virtue of giving during the holiday season. The continuation of this tradition serves a dual purpose: it brings happiness to children and instills in them the value of generosity, providing an early lesson that it is better to give than to receive.
