In Dalmatian parishes, during the Holy Week, one century-old custom stands out; the guarding of the Tomb of Christ. The guardians of the Tomb of Christ are young men who find honor and pride in this unique ministry. This custom also takes place in the Promina area since the end of the 19th century.

Liturgical dramas have been performed within churches for centuries and this is an opportunity to present similar, but yet different customs of parishes. What they have in common is a pious custom in which men, most often dressed in Roman soldiers uniforms, guard the Tomb of Christ and when they notice it's empty, they collapse and flee. This act is accompanied by a performance of parish church choirs.

In the Parish of St. Michael Promina – Oklaj, the guardians of the Tomb of Christ are dressed in traditional national costume, and they are also called gravediggers. Promina gravediggers have preserved their customs for more than 100 years. The will of the people to maintain this tradition could not be abolished, even by various political events. This custom/service begins on Holy Thursday, when the guards, after washing their feet (depiction of the Last Supper), commence their service. Four young men dressed in traditional costumes guard the Tomb of Christ. The leader of the gravediggers leads the entire ceremony and switches the guards every five minutes. The guards stand opposite each other, motionless, looking into each other's eyes. This lasts until the leader comes and hits a bench with a stick. The guarding takes place in a strict and pious atmosphere. Good Friday is the day of Jesus' passion and death. The Good Friday procession is one of the most famous customs of the Promina parish. It takes place through the entire village of Oklaj while the guards show their military abilities, such as marching. On Holy Saturday, after the completion of the Service of the Word, bells are rung inside and outside the church. Now begins the most beautiful moment in the service of the guardians. Everyone gathers around Christ's tomb and by taking off their hats, kneeling and running away (falling) from the church, they mark the resurrection. In front of the church, songs are sung in the old Promina way. At Easter, all the guards attend the Holy Mass in their traditional costumes.

On Easter Monday, the Festival of Žudije is traditionally held – a gathering of the guardians of the Tomb of Christ who nurture these customs in their parishes. The originator of the idea of this festival, which was launched in Vodice in 2001, is an academic photographer Šime Strikoman from Vodice, known for his millennial photographs.

April 22, 2019, the Festival of Žudije, the guardians of the Tomb of Christ, 19th in a row, was held in Oklaj and has brought in the guardians from 34 parishes from Croatia, Slovenia and Bosnia and Herzegovina.
