Is the christian religion in error in any way?

Christianity is not a religion. Christianity is a personal and life changing relationship with living God Jesus Christ

The biggest error in christian religion is "believing Jesus is a God ..

There's the bible, and then there's the culture, the stuff that individual churches added afterward. For example, my Southern Baptist ex-in-laws found it extremely offensive and repulsive that I breast fed my babies. They would get up and leave the room, even though they couldn't see my boob. That is certainly in error. I am an extremely modest person. Certainly God gave mothers milk to feed their babies. Somewhere they got all mixed up and decided that good Christian/modest women use formula.That's wrong.

Fundamentally ,yes

If Jesus is God, will you explain this Bible verse?

"The Father is greater than I." - John 14:28

"But in vain do they worship me, teaching for doctrines the commandments of men." - Mark 7:7

"I do nothing of myself" - John 8:28

neither came I of myself, but he sent me. - John 8:42

"And behold one came and said to him, Good teacher, what good things shall I do that I may have eternal life? So he said, "Why do you call me good? No one is good but One, and that is God alone. But if you want to enter into eternal life, keep the commandments." - Matthew 19:16-17

Study shows religion of Christianity set for extinction

A US study using census data shows that religion here and in eight other Western world countries is set for extinction.

Census data was taken from as far back as a century from countries in which the census queried religious affiliation: Australia, Austria, Canada, the Czech Republic, Finland, Ireland, the Netherlands, New Zealand and Switzerland.

The result, reported at the American Physical Society meeting, indicates that religion will all but die out altogether in those countries.

In New Zealand, it's thought around half of all Kiwis claim no religious affiliation.

Massey University Associate Professor of History Peter Lineham says in the 1950s, around 10% of New Zealanders had no religious affiliation. He says that increased to 45% in the 2006 census.

"Hopefully the 2011 Census will take place at some point next year and we'll know the latest figures, but it surely will have gone up to over 50%," he told Newstalk ZB.

Professor Lineham says the study would have very different results if the study looked at other countries.

"If they took any countries beyond the western countries they've named, they would actually have the opposite phenomenon of religion getting larger."

I'm sure the way that modern Christianity is practiced is not exactly the way it was meant to be practiced, so probably it is in some way or another.

Since people are not perfect its only common sense to predict errors in practice. Some more than others

No, because we have the Holy Spirit abiding in us and with us. The Holy Spirit does not make any mistakes. But human nature makes many mistakes and none of us is perfect, but God wrote the Bible using human hands and minds. God makes no mistakes.

Yes.! Cuz' There is no Proof That Jesus ever Existed.

and is Satanism Demons can Be Contact and Satan Can be Contacted too

That depends on who you're asking and what their understanding of history is.

In my understanding, Christians have made many mistakes in the past and present, Christianity itself still has a rather immaculate record.

Yes is promotes the belief in something no one knows is true or not. Thus producing false hope in all the believers.
