Which of the following is an example of monotheism?

Pentecostalism is an example of monotheism because it adheres to the belief in one God. This Christian denomination emphasizes a direct personal experience with God through the Holy Spirit, which aligns with the monotheistic principle of the existence of a single deity.

Monotheism, in religious studies, is the belief that there is only one God, a concept that is foundational in many religions, including Christianity. Pentecostalism not only embraces this belief but also engages in practices such as prayer, worship, and community gatherings that focus on their relationship with one God.

Atheism, being the lack of belief in any deity, does not fulfill the definition of monotheism. Rationalism, which focuses on reason and knowledge, does not specifically address the existence of deities and can be compatible with a variety of perspectives, including both theistic and atheistic views. Secularism, advocating for a separation between religion and public life, also does not promote the concept of a single deity.
