For the vigil Mass.
Summary: Jesus invites all who are thirsty to come to Him for living water. He speaks of the Holy Spirit, which would be given after His glorification, to those who believe in Him.
Gospel Acclamation: Come, Holy Spirit, fill the hearts of the faithful and kindle in them the fire of your love.
On the last and greatest day of the feast, Jesus stood up and exclaimed, “Let anyone who thirsts come to me and drink. As Scripture says: Rivers of living water will flow from within him who believes in me.”
He said this in reference to the Spirit that those who came to believe in him were to receive. There was, of course, no Spirit yet, because Jesus had not yet been glorified.
