洗礼 is a religious ceremony that symbolizes the purification and initiation of an individual into a faith community. It often involves the use of water, which represents cleansing and renewal. In many traditions, such as 基督教, 洗礼 is seen as a rite of passage that signifies a person's commitment to their beliefs and acceptance into the religious community. The practice of 洗礼 varies across different cultures and religions. In 基督教, it can be performed through immersion, pouring, or sprinkling water on the individual. Other religions, like 伊斯兰教, have their own forms of purification rituals that serve similar purposes, emphasizing the importance of spiritual cleanliness and commitment to faith.
