Three meals are required: Friday night dinner, Shabbat morning kiddush + lunch, and the third Shabbat afternoon meal. Each is a distinct Shabbat obligation.
Question 2
A very wealthy person who always eats gourmet food — does their Shabbat meal need to be different?
Even a person whose daily life is like Shabbat must make their Shabbat meals recognizably distinct — the point is the conscious act of honoring the day, not just the food quality.
Question 3
Is marital intimacy appropriate on Shabbat?
The Rambam explicitly includes marital intimacy as a form of oneg Shabbat. Shabbat is a day of joy and delight — this is an expression of that.
Question 4
Can you fast on Shabbat?
Fasting on Shabbat violates oneg. The exception: a disturbing dream (ta'anit chalom) — but even then, you must fast another day to "undo" the Shabbat fast.
Question 5
How does the Rambam conclude Hilchot Shabbat?
A powerful closing: Shabbat observance = the entire Torah. Idol worship rejection = the entire Torah. These are the two poles of Jewish identity — one positive, one negative.
