denominations, not be a proper Christian thing?

This is something to think about. Denominations (labels) may not be a proper Christian thing.

"By the way - We Are Not Denominational

We take this very seriously. We are not only non-denominational; we are opposed to denominationalism. Our rejection of denominational involvement results from our effort to do only what Jesus authorized. He did not establish denominations. Early Christians were not members of denominations; if they could be Christians without denominational connections, so can we and so should we.

Denominations wear names other than that of Christ. They have structure and activities that have no authority in scripture. And by definition they are divisions, whereas Christ desired unity. 'There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all' (Ephesians 1:4-6).

We are known as a church of Christ because we desire to give all honor to Him and because churches under His direction were known as 'churches of Christ' (Romans 16:16). We consider any other scriptural designation equally acceptable. We recognize no other head but Christ and have ties with no earthly organization or association of churches that would separate us from others who are Christians. All decisions are made locally in harmony with what we believe to be the instructions that Christ has given through His apostles."
