Conflict, migration, political instability, poverty, homosexuality and dialogue are amongst the many issues expecting coverage on the Pope’s visit to Africa this week. Despite questions and concerns about security, Pope Francis left Rome for a six-day trip to Kenya, Uganda and the war-torn Central African Republic (CAR) on Wednesday morning. Millions of Catholics, and a significant number of non-Catholics, are expected to welcome the Pontiff. Francis will visit a church that is growing in numbers – unlike much of the western church. He will be welcomed with jubilant African drumbeat and singing. But he will also find a continent and church that is struggling. By RUSSELL POLLITT.
