You can’t add to Christ without taking away from him. After reading, reading & re reading the New Testament for my seminary class this becomes overwhelmingly obvious.
There are all types of things that make people “feel” spiritual. Stuff like meaningless speculations about genealogies & certain words (2 Timothy), special spiritual revelations on worship (Colossians 3 -worship as the angels worship), a fascination with Judaism that results in practices that cultivate two sets of Christians (all of Galatians & most of Colossians), etc etc.
My confidence comes from & in Christ- not my spiritual experiences, not my ethnic heritage, & certainly not my adherence to the law.
Jesus PLUS nothing equal everything.
Jesus Plus anything = false Christianity.
One of the most interesting chapters in all the New Testament is when Paul compares the Galatians desire to adhere to the Law of Moses with a return to paganism.
Galatians 4: 8 Formerly, when you did not know God, you were slaves to those who by nature are not gods. 9 But now that you know God—or rather are known by God—how is it that you are turning back to those weak and miserable forces[d]? Do you wish to be enslaved by them all over again? 10 You are observing special days and months and seasons and years! 11 I fear for you, that somehow I have wasted my efforts on you.
Huh? I won’t give you the answer to that one. Research it for yourself.
Oh, and it has Eternal consequences. Be sure, Paul is talking about circumcision here, but his message is so much deeper & far reaching.
Galatians 5: Mark my words! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. 3 Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law. 4 You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace. 5 For through the Spirit we eagerly await by faith the righteousness for which we hope. 6 For in Christ Jesus neither circumcision nor uncircumcision has any value. The only thing that counts is faith expressing itself through love.
