"Your death, Lord, we denounce and your resurrection we confess". In this ancient hymn of the ecclesiastical community, the entire preaching of the Apostles is condensed. Christians are Christians if they proclaim the Cross of Christ and witness to the world his Resurrection. The first preachers of the Gospel considered that there was only one thing they had to make known: Christ and indeed crucified. To add that without his Resurrection, their preaching was words and phrases without content. Especially during the period of Great Lent and Easter the sermon is dedicated to the Cross and the Resurrection of Christ.
