Then would it make better sense to say COsubstantiation instead of CONsubstantiation in regards to what the Lutherns believe?
Yes it is commonly called cosubstantiation.
I think another way to put it is Catholics and Lutherans believe the bread and body, blood and wine are both there. The Catholics say we know “how” it is there -transubstatiation. Lutherans say we don’t know “how” they are just there together - cosubstantiation.
Lutherans do this quiet a bit with their theology. Were there seems to be a mystery, (like the last supper or predestination) we just leave it at that, don’t speculate much and go on faith.
More on the Last Supper from Lutherans:
- THE LORD’S SUPPER OFFERS AND CONVEYS FORGIVENESS OF SINS.
By these words forgiveness of sins, life, and salvation are given to us in the sacrament, for where there is forgiveness of sins, there are also life and salvation (SC VI, 6).
The people are also admonished concerning the value and use of the sacrament and the great consolation it offers to anxious consciences, that they may learn to believe in God and ask for and expect whatever is good from God (AC XXIV, 7).
- THE LORD’S SUPPER OFFERS THE TRULY PRESENT BODY AND BLOOD OF CHRIST.
It is taught among us that the true body and blood of Christ are really present in the Supper of our Lord under the form of bread and wine and are there distributed and received. The contrary doctrine is therefore rejected (AC X).
- THE LORD’S SUPPER STRENGTHENS FAITH.
Thus the Lord’s Supper was instituted in the church so that as this sign reminds us of the promises of Christ, the remembrance might strengthen our faith and we might publicly confess our faith and announce the blessings of Christ, as Paul says (1 Cor. 11:26), “As often as you do this, you proclaim the Lord’s death” (Ap IV, 210).
- THE LORD’S SUPPER IMPARTS POWER FOR CHRISTIAN LIVING.
For here in the sacrament you receive from Christ’s lips the forgiveness of sins, which contains and conveys God’s grace and Spirit with all his gifts, protection, defense, and power against death and the devil and all evils (LC V, 70).
- THE LORD’S SUPPER IS AN ACT OF THANKFUL ADORATION.
The principal use of the sacrament is to make clear that terrified
consciences are the ones worthy of it, and how they ought to use it.There is also a sacrifice, since one action can have several purposes.
Once faith has strengthened a conscience to see Its liberation from terror, then it really gives thanks for the blessing of Christ’s suffering. It uses the ceremony Itself as praise to God, as a demonstration of its gratitude, and a witness of its high esteem for God’s gifts. Thus the ceremony becomes a sacrifice of praise (Ap XXIV, 73-74).
- THE LORD’S SUPPER IS A CELEBRATION OF CHRISTIAN FELLOWSHIP.
After the Last Supper, as he was about to begin his bitter passion and death for our sin, in this sad, last hour of his life, this truthful and almighty Lord, our Creator and Redeemer Jesus Christ, selected his words with great deliberation and care in ordaining and instituting this most venerable sacrament, which was to be observed with great reverence and obedience until the end of the world and which was to be an abiding memorial of his bitter passion and death and of all his blessings, a seal of the new covenant, a comfort for all sorrowing hearts, and a true bond and union of Christians with Christ their head and with one another (FC SD VII, 44).
