The descent of the Holy Spirit at Pentecost is powerfully illustrated in this design, marking the birth of the Church. The apostles, gathered in prayer, receive the Holy Spirit, empowering them to spread the Gospel. The tongues of fire resting upon them signify divine wisdom, courage, and transformation. This moment fulfills Christ’s promise that His followers would not be left alone but strengthened by the Spirit. The scene serves as a reminder of the Church’s mission and the ongoing work of the Holy Spirit in the lives of believers, guiding them in faith and truth.
