This provides a pretty good summary for those who have a bit of trouble understanding the Holy Trinity and what it means that the Father, Son, and Holy Spirit are the same God.

Here the accompanying diagram helps clarify the nature of instances like the Lord's Prayer by pointing out that, while the three Persons of the Trinity are not each other, they all are one inseparable eternal God. As Athanasius worded it, "neither confusing the Persons nor dividing the Essence."

Note that "catholic" in the sense used in the Creed's English translation means universal and did not take on denominational connotations until the Great Schism of 1054.

There is no 'Holy Trinity' because the Jewish God does not exist.

There are only the Gods, mortals and the cosmos. There is nothing else.

The resurrection of Christ provides historical evidence on which Christianity can be proven or denied.
What evidence do you present for the existence of the Olympians beyond unbacked content of Hellenic epics?

The Gods are elemental beings that are built-in to the universe. The gods can take physical form if they please.
You can see the gods all around you. For if the gods did not exist and the Titans once again reigned supreme, you would not exist and the universe would be in a state of endless chaos.

There is no evidence of Yeshua bring devine or resurrecting. The whole idea of Christianity is based on the idea that the Jews and their practices, philosophy and ways are correct whereas Hellenism is a universal religion founded upon observations of how the world actually works.

The argument from design can just as easily used in favor of the Christian God. Moreover, adherents of the Israelite or Jewish religion proselytized as late as the Hasmonean era, and enough Romans were interested in Hebrew monotheism that such individuals became a significant demographic recruited by the early Christian Church.

As for the resurrection of Christ, His body must have been absent from His tomb else the authorities in Judea could have presented it to quell the growth of Christianity. His disciples are extremely unlikely to have stolen it due to the presence of Roman soldiers guarding the tomb and the improbability of the apostles dying for a nearly universally despised cause if they knew it to be fundamentally built on a lie.
