The miracle of Pentecost, as it pertains to speaking in tongues, marks a significant event in the founding of the Church of God in 31 AD. On that day, the phenomenon of speaking in tongues was introduced as a sign, where the disciples spoke in languages new to them, yet understood by the diverse crowd present. In Acts 2, this is depicted in its pure and unperverted form, as given by God, where the crowd expected to hear the Galilean dialect but instead heard their own native languages, demonstrating a dual miracle of speaking and hearing. This event allowed many people of various nationalities to comprehend the message in their own tongue, regardless of the language spoken by the disciples. The purpose of this gift on Pentecost was primarily to communicate the gospel of the Kingdom of God intelligibly to unbelievers and to serve as a visible and audible witness. The miracle ensured that, despite language barriers, the message was understood by all present, as evidenced by the listing of numerous regions and languages in Acts 2:9-12, all of which were known and common but new to the speakers. This event also served to confirm the gospel message, as seen in later instances such as Acts 10, where tongues reassured Peter and others of the validity of preaching to Gentiles, and in Acts 19, where it confirmed the message to those with partial understanding of salvation. The use of tongues on Pentecost and in subsequent events was always tied to a divine purpose, never performed without reason, and aimed at pointing to a significant message from God. Unlike the misuse seen in other contexts, the Pentecost event stands as the exemplary model of God's intent for this gift, focusing on clarity and understanding rather than confusion or personal display.
