"If ye had known Me, you should have known My Father also: and from henceforth ye now Him, and have seen Him. Philip saith unto Him, Lord, shew us the Father, and it sufficeth us. Jesus saith unto Him, Have I been so long time with you, and yet hast thou not known Me, Philip? He that hath seen Me hath seen the Father, and how sayest then, shew us the Father?" John 14:7-9
I want to make a few theological observations.
First, if you know Jesus you know the Father. God is not elusive or hard to find out or difficult to understand. The Father is known through the Son. Knowing Jesus is knowing God. There is no separation between God the Father and Jesus.
Secondly, Jesus said, "Have I been so long time with you , and thou hast not known Me,..." Jesus had only been with the disciples for three years and Jesus says that's a long time. I bring this up to settle some wrong thinking. I know people who have been a Christian for 20, 30, 40 years who have not grown in the faith, in some cases, not at all. They have hung on to a belief system that was developed years ago through their denomination and they never tested the waters or found out through personal Bible study if what they believe is scriptural. If three years with Jesus is a long time, what is forty years?
Jesus is revealing the Father here and the Father is revealing Jesus and you find out that when you see Jesus you see the Father. Why is it that we can't just accept the Word of God and believe what it says? I will say this. It is easier to believe the scripture than a whole lot of silly notions that religion has made up about God. When Jesus says, "He that hath seen Me hath seen the Father," I believe it. It settles many trinity questions for me. It settles my heart that I don't need to get to know three Gods, the Father, the Holy Spirit and the Son. I get to know one God who has revealed Himself to me through Jesus, "for in Him dwelleth all the fullness of the Godhead bodily." (Colossians 2:9)
And just one more thing. It's not blasphemy to question the/your church denomination's stand on a subject. It is wrong to take an oath or become a member of a denomination and then harbor differing theologies than that of your denomination, but to question certain doctrines through personal Bible study and prayer is of eternal importance.
Then to take your differences to your pastor and discuss them is not only appropriate but wise. Give your pastor a chance to speak to the issue and maybe even do some research and then make up your mind, but don't sit under anyone's teaching for a long time if you harbor vast differences in theology. It's not fair to your pastor or yourself. First of all if you have differing views from your pastor you probably aren't much assistance in building up your congregation and if you have differing views than your pastor you are stagnating in your walk with Jesus. Get to know your Bible and become part of what God is doing with those who are following Him.
