Justin Welby enthroned as 105th Archbishop of Canterbury Speaking about the miracle of walking on water he urged the Church not to be cowed by falling numbers ands said there was "every possible reason for optimism" about its future. Speaking after taking his pace on the Sixth Century throne of St Augustine, he said: "For more than 1,000 years this country has to one degree or another sought to recognise that Jesus is the son of God; by the ordering of its society, by its laws, by its sense of community. The Most Reverend Justin Welby after he was installed Sometimes we have done better, sometimes worse. When we do better we make space for our own courage to be liberated, for God to act among us and for human beings to flourish. Slaves were freed, factory acts passed and the NHS and social care established through Christ-liberated courage. The present challenges of the environment and economy, of human development and global poverty, can only be faced with extraordinary courage. He quoted the newly elected Pope Francis's recent call for people to be protectors of each other, the natural world, of the poor and vulnerable. The Prince of Wales and the Duchess of Cornwall arrive for the enthronement service And he also spoke about the legacy of his predecessor Thomas Cranmer, a protestant martyr burnt at the stake exactly 457 years ago today. Contrasting Britain's secular society with that of the Bible times he said: "Today we may properly differ on the degrees of state and private responsibility in a health society. But if we sever our roots in Christ we abandon the stability which enables good decision making. There can be no final justice, or security or love or hope in our society if it is not based on rootedness in Christ. Jesus calls us over the wind and storms, heed his words and we will have the courage to build society in stability.
