Progressive Threat to Christendom

Jesus Christ the same yesterday,

and to day,

and for ever.

Hebrews 13:8

"There are several dangers to biblical Christianity that have come about through progressive ideology.

Progressive ideology essentially stems from non-biblical positions about
--the nature of truth (that it is relative),
--the nature of people (that people are basically good)
--and the nature of scripture (that it should change with the times.)

The direct dangers are in the lowering of the truth of scripture into the realm of philosophical

relativism (there is no truth) and the general ideology of progressivism (a series of political and social causes guided by a regressive utopianism that seeks to constantly reinvent society.)
They tend to change how we view scripture; Instead of every word of the Bible being the inspired word of God that we regard as the authority over us, the progressive stands over the scripture and thinks of the scriptures as stories, that may or may not be factually true, and interprets and re-interprets the scriptures to fit with their own beliefs and ideas about how the world is.

Everything suddenly becomes up for revision,
--creation,
--moral teachings,
--life and
--liberty, even
--the atonement and
--resurrection of Jesus Christ.
Everything goes on the chopping block, maybe not all at once, but the door is opened to that possibility.

The teachings of Freud, Marx, and other atheist thinkers tend to be the roots from which progressive ideology grows and spreads.

Progressives tend to support politically: Bigger government, large administrative bureaucracies, democratic socialism, redistribution of wealth, unlimited welfare, abortion on demand paid for by others, free healthcare, free college, and unlimited unbridled immigration irrespective of national laws.

Key issues today that progressives advocate for are things like switching the church's position on gay marriage to support and affirm gay marriage. 
Another key issue would be legalizing and supporting abortion.
There are dozens of other issues pertinent, climate change, gun control, redistribution of wealth, .... Perhaps one of the most disturbing trends are the persistent attacks on religious liberty by progressives in the political sphere.

The trouble with progressive Christianity is that they take worldly love, set it above all else, and use it as a bludgeon to attack the truth statements of scripture. This is not love."
