It is important to separate the political and secular from the spiritual. But the actions of a General Convention can change nothing of the nature of Biblical Christianity, and its organization is not essential or required in any way for Anglican Christians to continue faithful. I won't go into a long list of Convention actions against communion here. We can talk about those if you wish, but I've already gone on too long. A final bit of practical advice.
Reform never begins at the top or with the large institution.
It begins with hearts seeking Christ and with families and parishes. We can always stay in communion with Christ, even if our circumstances are not what we would choose. Look at how the Prayer Book organizes an entire Christian life, from cradle to grave, day by day. Read the daily portions of Psalms. Read Morning and Evening Prayer.
