Mainstream Protestant churches have never been evangelical. The Anglican Church (Church of England) was evangelical a long time ago, but no more. Mainstream churches follow theological liberalism, which does not make the written Word of God the final authority. Man-made doctrines are common.
On the other hand there are non-Catholic and non-Protestant churches which were evangelical and also fundamentalist for many years, until they too started compromising on the Word of God. Evangelical churches supposedly focus on the Gospel, but if the Gospel is being watered down, then what's left? Even fundamentalist churches who stood firmly on the Word of God started compromising more recently. So over all things do not look very good, and perhaps may get worse. God must surely be very disappointed with these developments.
