Of course its ours to receive. We dont claim that God became a zebra to give grace to all zebras!
The issue is how does the Church recognize Baptism, Laying on Hands (for Comfirmation), the Lord’s Supper, Reconciliation, Matrimony, Ordination (as administers), and Annointing of the Sick?
The Catholic Church has recognized, professed, and practiced from the very beginning these as distinct forms of liturgical institutions from Jesus Himself. They are a common means for Jesus to establish the relative graces which they each impart. Prayer and faith are necessary elements to produce fruits of these graces in the recipient of these Rites and celebrations. Nevertheless, without proper disposition of the recipient, God’s grace is called on and offered personally, since our disposition is not the source or merit of grace. Therefore rejection of the grace received through these will incur greater judgment on account that more has been given!
Hebrews 10
How much worse punishment do you think will be deserved by the man who has spurned the Son of God, and profaned the blood of the covenant by which he was sanctified, and outraged the Spirit of grace?
Where do we see the blood of the covenant in the Scriptures??? And how can a person be sanctified by the blood of the Covenant, yet incur judgment and outrage the Spirit of grace???
Luke 22
And likewise the cup after supper, saying, “This cup which is poured out for you is the new covenant in my blood."
1 Cor. 11
Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord. Let a man examine himself, and so eat of the bread and drink of the cup. For any one who eats and drinks without discerning the body eats and drinks judgment upon himself.
