bible thumper

One who uses the Bible to attack/defame others' characters instead of as a guide to proper living. These people tend to be depressingly ignorant of anything else except the Bible and behavior as expected by the religious.

Originating from typically southern US fundamentalist Christian sects given to evangelizing in a very outgoing, rumbunctious way, often characterized by a religious bigot standing on a street corner, with or without foam around his mouth, shouting about how we should all turn to Christ, whilst vigourously thumping his soft covered bible for emphasis.
Their actions usually do more harm than good to their cause and bring into disrepute and ridicule those more reticent Christians.

(So called because some evangelists literally thump their Bibles to emphasize important parts of a sermon.)

A person whose religious beliefs include strict adherence to the Bible. He is likely to deliver angry sermons to anyone who believes differently, even if that "difference" means belonging to a church that disagrees with his interpretation of Scriptures.

1: Complementary context.
An enthusiastic preacher or person (might sometime literally thump the Bible) that seems to know the Bible well and not be wishy-washy and not to be poitically correct. Preaches fire and brimstone. esp. as a means of exhortation or rebuke.

2: In a negative critical context.
A preacher or a person that is hypocritically critical of others, as they are often worse of the people they are chastising. A person that uses religion to try to inoculate themselves from criticism. A con artist that does know much or some of the word of God, but does not abide by it, but tries to use religion to pretend to be an honest good person for personal gain. A religious whitewash. These individuals have a tendency to be on either end of the spectrum. Spending most of their time criticizing others; or they try to do token good deeds or token crusades to try to make themselves look like saints. Often they spent most of their time criticizing others to draw attention away from their own sins. Often they spend much time making token efforts, to draw attention away from their own sins.

A bible thumper is an EXTREMELY religious person. Not just a regular christian, most regular christians are pretty chill. A bible thumper would be:
-A person preaching in the subway or the sreets
-A person who does NOT respect your religious opinion

-Going to extreme measures to practice their religion.

The cause of many major wars, genocides, and crimes against humanity during the last 20 centuries.

A religious Zealot who pressures people to subscribe to their own religios beliefs, even after the target has said they are not interested. Mormons and Jehovah's Witnesses are particularly notorious Bible Thumpers.
