Is there a Bible verse about one church being better than another?

Question

One side of my family is rude to anyone who doesn't attend their church. Doesn't it say somewhere in the Bible that this is wrong and not one church is better than another?

Well I meant is that a Bible verse that tells us NOT to do this. I think they are completely wrong. I just want to show them they are wrong in the Bible.

Answer 1

Different churches, ones with different beliefs and practices did not formally exist at the time of the writing of the Bible. In the book of Revelation we read about seven churches which God speaks to in regards to how they are living up to being his Church. The Bible does have a lot to say about how we are to treat one another, churched or not. Perhaps you are thinking of one of the following:

There is no longer Jew or Gentile,[a] slave or free, male or female. For you are all Christians--you are one in Christ Jesus. Galatians 3:28

2Be humble and gentle. Be patient with each other, making allowance for each other's faults because of your love. 3Always keep yourselves united in the Holy Spirit, and bind yourselves together with peace.
4We are all one body, we have the same Spirit, and we have all been called to the same glorious future. 5There is only one Lord, one faith, one baptism, 6and there is only one God and Father, who is over us all and in us all and living through us all.
Ephesians 4:2-4

31Get rid of all bitterness, rage, anger, harsh words, and slander, as well as all types of malicious behavior. 32Instead, be kind to each other, tenderhearted, forgiving one another, just as God through Christ has forgiven you.
Eph 4:31

Answer 2

Try

Col. 3:16

Keep on teaching and admonishing one another with ... graciousness ...

Col. 4:5,6

Go on walking in wisdom toward those on the outside, buying out the opportune time for yourselves. Let your utterance be always with graciousness, seasoned with salt, so as to know how you ought to give an answer to each one.

Then there is the principle that a marriage mate can will over their spouse without a word, do to their chaste conduct. 1 Peter 3:1,2

Now remember if you show these scriptures to your family, you must also practice them.

1 Pet 3: 8 Finally, all of you be like-minded, showing fellow feeling, having brotherly affection, tenderly compassionate, humble in mind, not paying back injury for injury or reviling for reviling, but to the contrary, bestowing a blessing, because you were called to this course, so that you might inherit a blessing.

Answer 3

No disrespect, but what your family is doing is not religious...it's ignorant. No, there is not a Bible verse that tells you to discriminate against your fellowman....in fact, one of the greatest commands tells us to "love one another".
