If you are considering conversion to Karaite (Biblical) Judaism you must begin living by the words of the Torah. It is important to begin doing this as early as possible so you already have the mitzvot (commandments) internalized before you convert. In addition, one must become familiar with – and accept the principles of – the Tuv Ta’am (Declaration of Faith).
If you wish to convert to Karaite Judaism it is important to consider why being Jewish is important to you and why being Karaite specifically is important to you. You must also decide the best time to approach your family and friends with your desire to convert to Judaism. Generally, you will want to approach the subject as early as possible with your family and friends. If you have decided that you are ready to convert it is important for you to contact a Hakham or knowledgeable Karaite. It is important (if possible) to attend a Karaite religious service or ceremony.1
If you wish to convert to Karaite (Biblical) Judaism you must accept the three fundamental principles of Karaite Judaism.2
1. Believe in YHVH as the only God and renounce all others.
2. Believe in the Tanakh (Hebrew Bible) as the words of YHVH and the only religious authority – renounce all other writings, doctrines, as creeds as words of men.
3. Study and keep the Tanakh while striving to interpret the Tanakh according to its peshat (plain meaning).
By the covenant of Mount Sinai and the statutes of Mount Horev I will keep the holy appointed times of YHVH according to the New Moon and the finding of the Aviv in the Holy Land of Yisrael, when possible.2
It is important to live in a Karaite community if at all possible. All males must be circumcised in order to be accepted into the community. Circumcision can be performed by any qualified medical professional. If one is already circumcised proof from a medical professional will be required. All potential converts must make themselves and their homes pure (tahor). A period of learning with a Karaite community (or accepted program such as Karaite Jewish University) must take place lasting between six and twelve months. The potential convert must refrain from celebrating Passover but he/she is permitted to celebrate Chag HaMatzot (Festival of Unleavened Bread). Finally, upon the finalization of the conversion, the person must publically state that he/she intends to convert and shuns and other religious or faith systems.1 It is important that you join yourself YHVH by vowing before other Yisraelites by vowing that “YHVH is my God and Israel is my people.”2
If you wish to be recognized by the Karaite community and Israel you will need to take classes through the Karaite Jewish University or convert in Israel under Karaite auspices. If you already converted under Rabbinical auspices you will most likely be considered a Jew automatically in the Karaite Jewish world but it is best to inquire about your individual circumstances from one of the two link provided.
