Final answer:
An enduring legacy of the early Christian notion of love is the idea that priests and nuns should live celibate lives.
Step-by-step explanation:
The enduring legacy of early Christian notions of love includes the idea that priests and nuns should live celibate lives. This stems from the practice of asceticism, a form of self-denial observed by early Christians, which advocated for foregoing bodily pleasures to attain spiritual goals. Ascetic monks and nuns led communities and set examples of chastity and devotion, often in monasteries isolated from society. These practices have evolved into the clerical commitment to celibacy that persists in certain Christian denominations today.
