Sorry the concept of the trinity seems to be in doubt here but the bible does teach clearly. First what is the trinty? 1st there is only one God (Duet 6:4 the Hebrew Shema) God the father is God(Matt 6:9), Jesus is God (John 8:58),the holy sprit is God(Act 5:3-4).
The orthodox view of the trinty is that in the very nature of God exist three person (not like tom,mary, and jane) but three personally distinct ways of identifying each person in the Godhead.
Most people try to use the aurgument of 1+1+1=3 but the trinity is 1*1*1=1. This is why God can love the Son and the spirit that flows between them is the Holy Spirit. And no God did not kill himself Christ died for our sins.
Also just because Christ is labeled the Son of God does not in anyway suggests that Christ was somehow created read Hebrew 1-8 where God the father is calling Jesus God.
Remember one God(in nature or essence) revealed in three persons. Boy I am tired of typing but feel free to make comments because I know it is confusing. Amen
