Emunah and mistaken beleifs
Shalom k’vod harav.
How should we relate to someone with the following beliefs?:
a) The mabul was a local flood, and did not extend outside of a limited area in the Middle East
b) The “shishim ribo” the Torah refers to at yetzias mitzrayim is a metaphorical number and the actual number of those who left Egypt was far smaller.
Can this person serve as a witness? Is his wine yayin nesech?
A person who has mistaken beliefs about various details in the Torah, is not an apikores and as long as he is shomer Torah and Mitzvos and believes in the fundamentals of our faith [such as the 13 principles of the Rambam], may be a witness and does not make yayin nesech.
