What true doctrine is leading you to,
that is the goal.
Doctrine is a tool that leads us to being Christ like in character. That is the end all of the Christian faith-to be like Jesus in character (peaceable, kind, loving, patient, long suffering, etc). Keep that as the goal of your faith in this life and you will not be buffeted by the ever changing winds of doctrine blowing in the church.
"And He gave some as apostles, and some asprophets, and some as evangelists, and some as pastors and teachers, 12for the equipping of the saints for the work of service, to the building up of the body of Christ; 13until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ. 14As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine"-Ephesians 2:11-12
Keep the focus on growing up into Christ-likeness according to the fruit of the Spirit, and you will not be swayed back and forth by the ever changing winds of doctrines in the church.
If your focus is on knowing correct doctrine you're going to follow various winds of doctrines blowing in the church and you will be deceived into thinking that what you believe, instead of how you behave, is what pleases God.
