This is such a GOOD question... GOD bless you
LearningToLetGo for seeking to find PEACE... LOVE... and RESOLUTION. Your heart is tender and that is PLEASING before the Lord.
The answer is complicated ( in my opinion ).... in that ... ONE SIZE does NOT fit all.
For me... I had a need to walk away from my legalistic family because they are toxic to me. When I say this... I mean... the drama that ensues... the meddling they do in others' lives... the hypocrisy they live in because of hidden and un-confessed sin due to having to HIDE it from others etc... the list goes on.
It made me sick inside to be PRESENT with them for any length of time. THAT was a BOUNDARY I set for me... so that I could live my life in PEACE.
The above example is EXTREME because it involves my actual FAMILY. The result of this ( with regards to your question ) is.... In the scenerio of LEGALISM... there is NO focusing on correct doctrine. THESE people who follow do's and don'ts and harshly cast judgement on others are in a league all of their own. There is no reasoning with them... no speaking to them about things because they will fling scripture at you like it's spaghetti.
For me... the ONLY solution was to make a CLEAN CUT and MOVE on
for the sake of PEACE.
On a broader scale.... most doctrinal differences do NOT matter... For as much as I dislike the Catholic Doctrine... my landlords are Catholic... they have NO CLUE how I feel.... because I don't find it necessary to share. WE live together on the same property.... and I
love them with all my heart.
There is nothing wrong with being careful on WHAT we support as CHRISTIANS. In my opinion... it is necessary to stand against FALSEHOODS... but it does not mean we throw out the baby with the bathwater. ( Do people still use this term ?? ).
The bible tells us to live in PEACE... as much as is possible. What you are seeking is indeed possible and I think it does exist.
WE need to know our limitations. I have set mine very high but I am serious about GUARDING MY HEART.
There are some churches I would NEVER walk into.... and so.... I guess I would miss out on fellowship in the CHURCH BUILDING... but I would gladly break bread with these people. I just would NOT get into the doctrinal differences between us.
