Question
Hello, I am a gentile with question about Shabbat. Thank you for your time and emotional energy A friend of mine, whom is a Christian, uses the term Shabbat to describe his Christian prayer group, that gathers on Sunday night. They read the Old Testament and talk about g-d and rest. They gather and spend time as friends. I argued with him that using this phrase and this practice is inappropriate. In my understanding, Judaism is a closed practice and there are certain elements that should not be performed or used by non-Jews. It morphed into a pretty big argument between us with his point being that Jews cannot “own” the concept of rest and Shabbat. I want to be sure I am not incorrect. I do not want to be sharing false information. I have googled extensively and I am seeing so many Christians talking about Shabbat or Sabbath. I don’t remember this being a thing when I was growing up Christian. Thank you for your time.

Question
Dear Rabbi, I was watching the funeral of a fallen Israeli soldier the other day at the military cemetery at Mount Herzl in Jerusalem. It was sad and I’m sure mine were not the only dry eyes. While watching, I remember hearing a custom for anyone who visits a grave to place a small stone on the headstone. What is the reason for this practice? Thanks, Rabbi!

Question
Does riding a bike on Shabbat violate any biblical laws, or only rabbinical? If one has extenuating circumstances that require traveling by some type of vehicle on Shabbat (such as visiting the sick), and a bike can meet that need, would the use of a bike be a lesser violation than driving a car? Or has one equally broken Shabbat?
