For many Christians around the world, today’s Palm Sunday marks the beginning of the Holy Week.
Palm Sunday is the final Sunday of Lent that commemorates the arrival of Christ in Jerusalem, days before he was crucified.
In Port Moresby, St Joseph parishioners did a reenactment of the Gospels of Jesus entering Jerusalem before his death.
Palm Sunday is known as such because the faithful will often receive palm fronds which they use to participate in the reenactment of Christ's arrival in Jerusalem.
Main celebrant, Fr John Auram, during his homily, said Palm Sunday is a time to reflect on our lives as Christians.
"What we have done as part of our service to God and towards the people we love," he said.
He said it is also a time to be grateful of the blessings we receive from our fellow Christians.
He encouraged parents and teachers to teach their children the way Christ was taught and the importance of observing days in the Lenten Season.
Parishioners waved palm branches during the procession into the church where the main Mass began.
Palms are widely recognised symbols of peace and victory, hence their preferred use on Palm Sunday.
