A good definition comes from Wikipedia.org:
*Modernism refers to theological opinions expressed during the late 19th and early 20th centuries, but with influence reaching into the 21st century, which is characterized by a break with the past. Catholic modernists form an amorphous group. The term “modernist” appears in Pope Pius X’s 1907 encyclical Pascendi Dominici Gregis. Modernists, and what are now termed “Neo-Modernists,” generally do not openly use this label in describing themselves.
Modernists came to prominence in French and British intellectual circles and, to a lesser extent, in Italy.The Modernist movement was influenced by Protestant theologians and clergy, starting with the Tübingen school in the mid-19th century. Some modernists, however, such as George Tyrrell, would disagree with this; Tyrrell saw himself as loyal to the unity of the Church and disliked liberal Protestantism.
Since Pope Paul VI, most Church authorities have largely dropped the term “modernism,” preferring instead in the interest of precision to call beliefs such as secularism, liberalism relativism by their several names. The old term has however remained current in the usage of many Traditionalist Catholics and conservative critics within the Church.
But is it Christian?
No! Modernism is anti-Christian! Let’s look at some of its teachings that are being pushed upon the youth of today:
– The scriptures are denied as being “God Inspired.”
– If man ever had fallen, he fell upward instead of downward and has been slowly evolving upward since
– It denies the blood redemption
– It teaches there is no Hell
– It teaches no eternal punishment
– It teaches universalism and all will be saved in time
– It denies the new birth
As you can see, modernism is a dangerous belief and paving the way to an eventual Hell!
1 Corinthians 15: 12-19 (NASB)
12 Now if Christ is preached, that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, not even Christ has been raised; 14 and if Christ has not been raised, then our preaching is vain, your faith also is vain. 15 Moreover, we are even found to be false witnesses of God, because we testified against God that He raised Christ, whom He did not raise if in fact the dead are not raised. 16 For if the dead are not raised, not even Christ has been raised; 17 and if Christ has not been raised, your faith is worthless; you are still in your sins. 18 Then those also who have fallen asleep in Christ have perished. 19 If we have hoped in Christ in this life only, we are of all men most to be pitied.
