On 15 December 2009, Pope Benedict made public some "clarifications" (revisions?) he made to the 1983 Code of Canon Law in a motu proprio titled, Omnium in Mentem. To date, no English translation of the motu proprio has been made available, until now that is.
We are happy to have said document in English thanks to the work of Mr. Paul Haverstock. You can read it here: Omnium in mentem trans Haverstock.pdf.
While Mr. Haverstock's translation is not an official translation of the Holy See, it is a gift to have it now in well written English.
Thanks.
The Official translation is available from the Vatican Website: http://www.vatican.va/holy_father/benedict_xvi/apost_letters/documents/hf_ben-xvi_apl_20091026_codex-iuris-canonici_en.html
Thanks for the email, Fr Thomas. Yes, I am aware of the Vatican translation of Omnium in Mentem and will make an updated NB on the original post. PAX!
