The concept of God as Trinity – 3 in 1 and yet one – is fundamental to Christian belief. In fact it is a central tenet of all mainstream denominations. It is interesting, then, that God is Trinity is never explicitly mentioned as such in the Scriptures. We have to infer that by putting together the pieces from verses such as the well known “Grace” from the end of 2 Corinthians:
“May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all.” 2 Corinthians 13: 14 NIV.
From that verse we see the Father, Son and Holy Spirit working together as a unity and yet with distinctive roles. If we consider the story of the Bible from beginning to end, we see the same cooperation. If we take salvation, we see that each member has a particular role to play – the Father as the one who loved and sent, the Son who willingly sacrificed himself, the Holy Spirit who applies the work done in the life of believers.
Each member of the trinity is equal, none is subordinate to another, but at times they take on subordinate responsibilities – Jesus humbled himself to take human flesh, the Spirit glorifies Christ. And yet they are equal. And they are three persons and yet one.
Can you get your head around it? Neither can I – and I don’t think we’re meant to!
