Some people suggest these negative trends in the USA began around 1900. Before that the USA had been WASP more as a religious identity more than an ethnic group. Apparently evolution was a big issue and the Bible being pushed out of schools.People even then were beginning to feel alienated. from the larger society.Then there was the push back which was mainly from Azusa Street and Aimee McPherson. But for some reason that seems to have had a very limited effect. The Leftward trends just kept going. My feeling about this is that the basic doctrine was really not as solid as the people like McPherson thought in the first place. As I have pointed out before letting Paul into the canon was like letting an ax into the piston engine.The basic Doctrine up until that time had been "the Constitution and the Word of God." But in the word of God itself as understood by Christians there were already tendencies of "anti Law." [anti-nomian-ism]. This charge was leveled at Protestants in particular after Martin Luther and it seems to me to be perfectly justified. In any case, this anti Law tendency just got worse over time. In Paul's time when Paul saw the effect of his aninomian letters, he pulled back and tried to correct the situation with limited success. But the antinomian letters are still there for anyone to read and still believe they are reading the "Bible".
