They were all in one place together

“When the time for Pentecost was fulfilled, they were all in one place together. And suddenly there came from the sky a noise like a strong driving wind, and it filled the entire house in which they were. Then there appeared to them tongues as of fire, which parted and came to rest on each one of them. And they were all filled with the Holy Spirit and began to speak in different tongues, as the Spirit enabled them to proclaim.” (ACTS 2: 1-4) 

God expects from the Apostles only one thing—“they were all in one place together.” Everything else came from Him: “tongues as of fire, which rest on each one of them” and “filling with the Holy Spirit and speaking in different tongues.” The same happens with family when “they are all in one place together.” God created the Church as a community and marriage, “the domestic Church,” also as a community, and whenever the Holy Spirit comes, it is always to build community. And this is the most unique and prestigious gift of the Holy Spirit—unity and community; it is much more important than all the amazing gifts (like speaking in different tongues) we can receive with His coming.

“Come, Holy Spirit, fill the hearts of your faithful and kindle in them the fire of your love.” (Gospel Acclamation)
