What's the difference between the Nicene Creed and the Apostles' Creed? They were written in two different times. The Apostles' Creed is the oldest creed, and that can be used at Mass on Sunday and Holy Days.
It is one of the options. Now, the Apostles' Creed is what we normally say, of course, when we say the Rosary or the Divine Mercy Chaplet. The Nicene Creed is what we normally say on Sunday, but they can be interchanged when it comes to Mass. The Nicene Creed was from the Council of Nicaea, and so it had to deal with, you know, the divinity of Jesus, and so that's why in the Nicene Creed, it's God from God, light from light, true God from true God, begotten, not made, a little different now, but it's the same thing. It's trying to say that Jesus Christ is God, so it's dealing with the heresies of the time of Nicaea when the council was brought together, and they came out with this creed, so The oldest of creeds is the Apostles' Creed, which most churches use, Catholic and Protestants, and even a lot of Protestants will use the Nicene Creed, even though it's later, but it was really trying to develop the theology and making sure we made clear statements about what we mean about Jesus being God, primarily, but there's more there.
So, a good question. Thank you for asking.
