What about "trinity" - is that mentioned anywhere in the Bible? (just askin')
You're asking the one person on this site who wouldn't know. :)
no, the rowd Trinity is not in th eBible.
The Trinity is a description of the 3 attributes of Gd as
1.Father
2. Son
3. Holy Spirit
It came about because of the way each is described in their Power, act of having personal attributes such as personality and ‘personhood’ (not God is a person, but each of these three have a distinct mention as someone separate and distinct from each other), and of the rank or power that each has and how these powers of the powers associated only with God, such as omnipotence, ability of being everywhere at once, knowing everything at once, being able to perform miracle like transformation of many or one at once by their own will, unlike an Angel which in all written record only do one thing at a time and do it because they were told to.
Start with that. It is an easy concept and a difficult one at the same time. :)
