What is the Greek used for the word “water” and does it mean literal water in the Greek?
Two Protestants brought this up to me about the Greek, so in Greek does it mean literal water?
For Catholics the answer is Yes, it does mean water, specifically the water of baptism. Here are the three main references in the CCC:
*1215 This sacrament is also called “the washing of regeneration and renewal by the Holy Spirit,” for it signifies and actually brings about the birth of water and the Spirit without which no one "can enter the kingdom of God."7
1225 In his Passover Christ opened to all men the fountain of Baptism. He had already spoken of his Passion, which he was about to suffer in Jerusalem, as a “Baptism” with which he had to be baptized.22 The blood and water that flowed from the pierced side of the crucified Jesus are types of Baptism and the Eucharist, the sacraments of new life.23 From then on, it is possible "to be born of water and the Spirit"24 in order to enter the Kingdom of God.
See where you are baptized, see where Baptism comes from, if not from the cross of Christ, from his death. There is the whole mystery: he died for you. In him you are redeemed, in him you are saved.25
1238 The baptismal water is consecrated by a prayer of epiclesis (either at this moment or at the Easter Vigil). the Church asks God that through his Son the power of the Holy Spirit may be sent upon the water, so that those who will be baptized in it may be "born of water and the Spirit."40*
