Now when someone explains Trinity
by exampling out Egg structure;
this might be comprehendible to a Polytheistic Believer but
a Monotheist (Jew or Muslim)
would definitely ask you this…
Egg is an egg as long it’s together.
The moment it’s “shell,” “white,” and “yolk” are separated---
it’s no longer an egg!
Either it is egg-shell, egg-yolk or egg-white,
but no longer an Egg anymore,
or a complete egg!
Moreover, all the 3 components are having one physical form,
all the egg-components are made up of “substance”---------
Whereas as per your theology
‘The Spirit’ and
are in different physical forms!
This can be easily destroyed because if they believe this then this means that god is created. In the Islamic tradition God is uncreated so if Christans believe this then God created himself in three parts, then he could not be God because God cannot create himself. God is uncreated.
So this is easily is destroyed. Know that all Christans have is argumentation and that's it there is nothing solid. Even if you tell them this they will refuse and try to worm their way out of this.
