Is there a such thing as a sect of Judaism that believes only the Torah, and not any other traditional writing

Question

...in other words, strictly the old testament and not anything outside of that...

Answer 1

yes, the Karaites

Answer 2

The Karaites,who were not considered as being real Jews by many Jews,rejected the authority of rabbinic commentators and of the Oral Torah(Mosaic Tradition).They arose in the Middle Ages and still exist and go by the "Tanach Alone".Karaites were never part of mainstream Judaism and other Jews pointed out that they swiftly began interpreting the OT in light of there own tradition and authorities after rejecting Rabbinic Tradition and authority of the Chair of Moses.
The Sadducees and Samaritans only had the Written Torah,the first five books of the OT, as sole Scripture and rejected Pharisee Bible canon and tradition.

Answer 3

As others have said the Karaties.

Their are an estimated 2,000 Karaties in the United States. With about 25,000 world wide (most of those in Israel).

Unfortunately the Karaites have been their own worst enemy. With complete freedom to interpret the Bible as they wished they ended up breaking apart into smaller sects hurting their own unity, and eventually significantly reducing their numbers.

Answer 4

Um, the old testament includes many other writing besides the five books of moses. So I suppose the answer to your question is no.
