Dear Bishop
If you were serious about wishing to bring about the type of society you describe, you would say two things: 
1:   The ANC has let the country down by not curtailing corruption or removing Zuma from office, and can no longer be trusted to fight for the rights of the poor and disadvantaged; and
2:  Accordingly, we as the SACC suggest you vote for another party which is not so manifestly corrupt. 
Voting is the one civic action that each and every one of us can undertake, and your guidance in exercising this vital civic duty would go a long way towards ensuring the outcomes you espouse in your article. 
Regards
