What you are over-looking is that some people will interpret Scripture according to what they want to believe.
Scripture says so.
You can show them whatever proofs you want - it won’t make any difference because they chose to believe what pleases them.
Scripture says so.
However, I do look to see what the author originally meant. I look at the context. I look at how the listeners responded to the words that were said. I look up the meaning of the original word used because too often the English provides a poor translation. I research the culture (sometimes) And I cross reference OT and NT.
But the most useful tool I have found is prayer.
There are no “Sola Scriptura” proofs in the Bible. This is a fiction made up by Luther, Calvin, and the Protestants of the 16th Century.
If you look at the Scriptural proofs of the Real Presence in the Eucharist, look at the reaction of the listeners in John 6. They clearly understood that Christ was talking to them of giving them his Flesh to eat, and his Blood to drink. “And many walked away for this was a hard saying”.
Look at the words of the Eucharist in the Gospels. The institution of the Sacrament of Penance. The Founding of the Church on Peter. The Promise of the Paraclete, and the protection from error.
You take the Scriptures to mean what you want them to mean, or, not to mean what they say.
Private interpretation serves two masters, both of which are erroneous, both of which keeps you from the truth.
So, re: the Eucharist, for example, how do you interprete:
Ex 12:21-28 Passover Lamb
Mt 26: 26-28
Mk 14: 22-25
Lk 22: 14-20
Jn 1: 28-30
Jn 6: 35-58
1 Cor 10: 16
1 Cor 11: 23-29
Jn 1: 28-30
You take the New Testament passages on the Eucharist not to mean what Catholics live and practice from the times of Acts, cause it would mean you are wrong.
