Question: I see that many people are particular to write ‘G-d’. Is there anything wrong with writing ‘God’ out fully?
Answer: There is no issue in writing or printing Hashem’s name properly, providing one knows that it won’t be destroyed.
Rambam (Yesodei Hatorah 6:1) writes that there are 7 sheimos (names of Hashem) that mustn’t be erased. There is no issur in erasing a kinui (moniker) such as chanun or rachum, etc. R’ Akiva Eiger (YD 276:9 quoting the Tashbetz) writes that as translations of sheimos have the status of kinuim, there is no issur in erasing them either.The Shach (YD 179:11) writes that Hashem’s name in a foreign language is not considered sheimos and thus may be erased. Likewise, the Mishna Berura (85:10) writes that the issur only applies to erasing sheimos in Hebrew (See Minchas Chinuch 437:5).
Nonetheless, the Aruch Hashulchan (CM 27:3) urges people to be extra particular when writing letters with sheimos even in a foreign language.Thus, while it is not strictly forbidden to write or erase the word ‘God’, it is good practice to write ‘G-d’ and such writings must still be treated with respect. Thus, rather than thrown in the bin, a paper containing the word ‘God’ should be recycled with other documents, or wrapped before disposal (See Igros Moshe OC 4:39).
