Sound doctrine is a thing of the past...

Today's church embraces modern doctrines that are not found in the writings and teachings of the first century church nor in scriptures.

Self-centered and self-pleasing doctrines such as one saved always saved (AKA the preservation of the saints) and the pre-trib rapture are taken out contorted and noncentextual scriptures in order to itch the ears of today's humanist ChristIan.

Show me scriptures that state the contrary.

While you are at it please also provide any first century writings that clearly support these doctrines as well.

We are told to:

Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine. [3] 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; [4] And they shall turn away their ears from the truth, and shall be turned unto fables. [5] But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry. 2 Timothy 4:2-5

We are also told to:

...Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls. But...today's church, just as the people during Jeremiah's time, is saying:...We will not walk therein. Jeremiah 6:16
