How did you arrive at this conclusion?
On what are you basing this? Do you have a source that counters the article's poll in the OP?
I find the poll lumps both Christendom's teachings and first-century teachings as being one and the same.
We can base the teachings of Christendom on church customs or church traditions just taught as being Scripture.
We can base the teachings of Christianity on the first-century teachings of Christ as found in Scripture.
Matthew 25 follows along with Matthew 24.
Both chapters Matthew 25 and Luke 21 describe, besides all the bad news on Earth, there would be a world wide or international proclaiming being done about the good news of God's kingdom (Daniel 2:44).
Never before in history has Matthew 24:14 and Acts of the Apostles 1:8 reached such a grand scale as today.
I find of interest that Luke 21:11 even mentions the type of earthquakes that would be happening now with using the adjective ' GREAT ' to describe the type of earthquakes occurring before the end comes of badness on Earth.
Jesus never taught that such bad things were from his God, but just that such things would be happening before God will bring to ruin those ruining Earth as mentioned at Revelation 11:18 B.
