As “Preach” begins its Lent 2026 series, Ricardo da Silva, S.J. sits down with liturgical theologian Anne McGowan to ask a foundational question: what is Lent for — and how do these practices reshape our faith, not just our habits, for six weeks? Together, they trace its history from a two-day fast in the early Church to the 40-day season we know today, and explore its theological arc in the Sunday lectionary—from temptation and transfiguration to water, light and life, and finally the passion that leads into Easter, where new Christians are baptised and the faithful renew their baptismal promises.
