Claire McCollum is in Bognor Regis to celebrate Pentecost with the growing congregation of St Wilfrid’s Church on the seafront. Claire meets Christians taking the plunge and celebrating their faith by being baptised in the sea. The vicar, Rev Joel Mennie, dons his wetsuit to lead the baptisms and reflects with Claire on the new life he’s seen in the church and the power of the Holy Spirit. And in London, to celebrate Pentecost being 'the birthday of the church', Christian baker Chinelo Awa bakes a cake with a twist for the occasion and shares how it represents her very personal journey of transformation.
