Can a divided house remain standing (denominationalism)

The concept of a denomination, as commonly believed today, involves all the following elements:

* Each denomination is an affiliation or confederation consisting of a number of local churches. (Southern Baptist, Calvary Chapel, Catholic. Methodist, etc...)

* Each denomination has its own peculiar name, doctrine, organization, plan of worship, etc., which distinguishes it from other denominations.

* Each denomination claims it is composed of Christians, but it does not claim to contain all faithful Christians. Each denomination believes there are faithful children of God in other denominations. "There are saved people in all the denominations." "We're all going to heaven, just by different routes." 

Okay stop, the bus in case any of you didn't catch that. let try it again:"We're all going to heaven, just by different routes." Hmm, There is only one way to heaven, and that is through Jesus Christ.by Lee Strobel. Okay is Lee Strobel  contradicting these denominatsionlist? Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. (John 14:6) Wait a second is Christ also saying that there is only one path to Heaven? So why do we have all these denomination again? oh wait I know,"One church is as good as another." It's just a matter of personal preference, like different kinds of cars, colors of clothes, etc. So "join the church of your choice." Didn't know Christ was like Mcdonalds that you could have salvation the way you wanted it.  To bad someone didn't tell Job that cause I'm sure he would choose not to suffer, or told Jeremiah that it really was all about his wants and desires instead of God's will being done.

Ask any informed denominationalist, and he will confirm what we have said. Ask: "Are there saved Christians in your denomination?" He will say, " Why of course." Ask: "Are there Christians in other denominations, who will go to heaven?" He will say, "Certainly there are." Ask: "Does one have to be a member of your denomination to go to heaven?" He will say, "No." So each denomination claims to consist of some Christians, but not all Christians.

A denominational preacher once said the following in a letter:

"There is only one 'holy Christian Church,' of which Christ is the Head, but it is now made up of many denominations ... But faith in Christ is the first criterion of membership in the holy Christian Church, and we feel that such believers can be found in all Christian denominations."
