Eph 2:19-22
Brothers: you are no longer aliens or foreign visitors; you are fellow-citizens with the holy people of God and part of God’s household. You are built upon the foundations of the apostles and prophets, and Christ Jesus himself is the cornerstone. Every structure knit together in him grows into a holy temple in the Lord; and you too, in him, are being built up into a dwelling-place of God in the Spirit.
On this day on which we celebrate the Feast of an apostle, it is worth meditating a little on the Church.
