Question

Justice in the World was written in 1971 but by whom? I think it was written by the Synod of Bishops, but who were they? is there a list of the synod of bishops of 1971?

OK MY QUESTION IS...

Answer 1

A synod (also known as a council) is a council of a church, usually a Christian church, convened to decide an issue of doctrine, administration or application. An ecumenical council is so named because it is a synod of the whole church (or, more accurately, of what those who call it consider to be the whole church.)

The word comes from the Greek συνοδος meaning "assembly" or "meeting", and it is synonymous with the Latin word concilium — "council". Originally synods were meetings of bishops, and the word is still used in that sense in Catholicism and Eastern Orthodoxy.

Sometimes the phrase general synod or general council refers to an ecumenical council. The word synod also refers to the standing council of high-ranking bishops governing some of the autocephalous Eastern Orthodox churches.
