In response, the Central Committee met digitally this morning, in consultation with Bishop Robert (Church of England) and Bishop Mark (The Episcopal Church). It made the decision to suspend all public worship and parish activities in Anglican and Episcopal churches in Belgium from 14 March until 3 April. This decision was made for the public good as part of the ongoing national and global attempts to limit the ill effects of the coronavirus pandemic. We will post further news when we have further information.

The Central Committee's letter to Anglican parishes is here.

Here is a letter from Bishop Robert.
