Can someone of Orthodox beliefs attend services at a Reform synagogue? If so, please tell some things to expect at a Reform Shul different from an Orthodox.
Quite aside from any issues of appearance (which I understand to be quite serious, among the Orthodox, with respect to non-Orthodox services), you will not be yotzei because they will not do the prayers fully and in the manner you expect.
Customs vary, but I've been going to Reform services for years and have visited a few different synagogues, and here's what that experience suggests:
- Some prayer texts will be altered. For example, part of Aleinu is usually omitted, the imahot are added to the avot in the t'filah, and "m'chayei meitim" might instead be "m'chayei hakol".
- A mix of Hebrew and English will be used. Not all English will be a faithful translation.
- Sometimes statutory prayers will be replaced with "creative" readings (poetry, etc).
- Reform congregations are egalitarian, so you may see men or woman in the various roles (sh'liach tzibur, ba'al koreh, aliyot, etc).
- There will probably be more "orchestrated" reading than you're used to (everybody reads together, or call and response).
- There may be a lot of singing, by both men and women.
- Some "creative" English readings may be inserted at the beginning.
- Candles will be lit and kiddush chanted, regardless of the hour. (Reform congregations rarely follow the sun; services are at fixed times throughout the year and, except for "tot shabbat" and such, are unlikely to start before 6.)
- Kabbalat shabbat, specifically the psalms, will likely be truncated and some omitted.
- Lecha Dodi will be sung, but maybe not all nine verses.
- Shalom Aleichem will be sung.
- In kriat sh'ma, the service will likely go from the v'ahavta paragraph straight to l'ma'an tizkaru. The first b'racha after the sh'ma is likely to be altered or absent.
- In the t'filah you can expect avot, g'vurot, and atah kadosh to be as normal (except for variations noted above for "all services"), but after that some parts may be condensed or altered. Sometimes the congregation sits after atah kadosh.
- There might be a torah service, though this is on the decline.
- After la'asok b'divrei torah, the specific texts studied may be different from what you expect.
- P'sukei d'zimrah will likely be condensed (some psalms omitted and parts of nishmat through the end will probably not be done).
- In kriat sh'ma, some will say the tzitzit paragraph and some not.
- Changes in the t'filah similar to those on Friday night.
- The torah reading might not include the entire parsha.
- Musaf is not done.
