instead of proof texts, I think it is better to engage in a conversation of what a Sacrament is.
It is an outward sign of invisible grace.
Marriage is a Sacrament because it is an outward sign of Christ and the Church, (see Ephesians 5:22 onward).
As such, there is a parallel between what the sign of marriage is and what the sign of Christ and the Church is.
A man leaves his Father and Mother. He makes a committment.
In the case of Jesus on the cross, Jesus said, Father, not my will but your will.
"He cleaves to his wife"
He makes a covenantal vow to give his very life and body fully and completely to each other.
Jesus gave his life and his body fully and completely through the scourging, beating, carrying his cross, and hanging on the cross.
"And the two become one flesh"
The married couple gives themselves to each other. They consummate the marriage.
Jesus in John 19:26 said, It is consummated.
he gave his very life for his Church.
(this is what happens when we participate in Holy Eucharist).
Here is the main point. In giving his life, He consummated the covenant and what happened; water and blood flowed from his side.
The Fathers of the Church saw in this, the transmission of new life. Water is teh life of Baptism, blood is the Eucharist.
Seen in this way, marriage is viewed in Eucharistic terms where Jesus gave his life, totally and completely without reservation to His Bride the Church, and his bride wholly and completely accepts the life of Christ and from it springs new life, the rebirth of Baptism and life sustaining Eucharist.
Imagine if Christ had contracpeted so that he held back some of his full and total life giving self on the cross?
What if he put a barrier so that the fruits of his life could not give life to the Church?
Imagine if there was a barrier to the grace contained in the Eucharist. The grace that brings with it, eternal life?
This is really what contraception is!
Contracpetion needs to be seen in light of the total and complete self giving of the bridegroom Christ to the bride (Church), and the total receptivity (we receive his body and blood in the Eucharist) of the Church in reciving Christ’s life.
And this reception brings life, spiritual life.
In the context of Eucharist, contraception is contrary to CHrist’s total and complete self-giving on the cross.
