I can see that you are going to be an unnecessarily difficult discussion partner. Okay, here goes, using the Nicene Creed:
This summarizes the doctrine of creational monotheism. That is, God alone - absolutely without advisors or collaborators or assistants or servants - created all other things. This idea Christians inherited directly from their Jewish heritage.
This summarizes the relationship of the divine in the Son with the divine in the Father. It says that Jesus was begotten, but not made, of God. He's of "one substance" with the Father, which basically means that although there is one and only one God, both the Father and the Son are equally divine. This does not represent a division of God into two separate beings or parts.
Here we have a summary of Pneumatology (doctrine of the Holy Spirit), ecclesiology (doctrine of the Church), soteriology (doctrine of salvation), and eschatology (doctrine of ultimate ends). We find that the Holy Spirit is distinct from the Father and the Son, yet together with the Father and the Son is worthy of worship. The unity of the Church, based on a succession from the original apostles is affirmed. There is one baptism for the remission of sins (salvation), and the hope of a new world to come is stated.
So as you can see, the creeds are theologically rich statements that bear plenty of unpacking. But they are certainly useful summaries of biblical doctrines. The creeds don't add to scriptural teaching. Now, you may disagree whether these doctrines are in fact taught in scripture, but that's not the point. The point is that they are intended to do so.
So there, you have your examples made more explicit.
