In order that I might properly frame a reply, is your main argument from tradition or from the Greek text ?

[Kolokotronis]

Both actually, and a third; First, Greek was my first language, or at worst contemporaneous with English. I've read, spoken and studied ancient, modern and koine Greek all my life (well, I haven't spoken ancient, except to confuse profssors in college many, many years ago!)Tradition developed from the people who wrote and spoke the Greek text. The same Tradition determined what became the Canon of the NT. English is a limited language when it comes to Christian theology. Even Latin is, though not so limiting as English. For example, what does "omoosios tou Patri" mean in English?

Not sure what you mean. Which argument? That "brothers" mean also cousins, or that in certain cultures to this date the same is true, and always has been?
