Popularity and prosperity became more important than Gospel truth because the Great Apostasy had taken over the majority of churches worldwide.
The sad truth is that on Christian forums today there are more heresies being promoted than sound doctrine, and the true and full Gospel of Christ. The same is true for many *Christian* websites, broadcasts, podcasts, and TV programs. All of this was already predicted by the apostle Paul, and we are seeing it all around us.
For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; And they shall turn away their ears from the truth, and shall be turned unto fables.... This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,traitors, heady, highminded, lovers of pleasures more than lovers of God; having a form of godliness, but denying the power thereof: from such turn away... Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; Speaking lies in hypocrisy; having their conscience seared with a hot iron...(2 Tim 4:3,4; 3:1-5; 1 Tim 4:1,2)
