Indeed! You sound like me now. If only that was the basis for all Catholic doctrine, for distinctive Catholic teachings are not manifest in the only wholly inspired substantive authoritative record of what the NT church believed (including how they understood the OT and gospels), which is Scripture, especially Acts thru Revelation.
And as regards Catholic Eucharistic theology, we should ask:
Where in all of Scripture did Jesus Christ appear as an inanimate object, which by all tests of physicality would be just that? 0
Where in Scripture is the manifest physicality of Christ emphasized as establishing who the real Christ was, in contrast to one whose bodily appearance did not correspond to what He physically was? (Is. 53; Lk. 24:39; John 20:27; 1 John 4:2; 5:6,8)
Where in all of Scripture did the words of the Lord's supper necessarily teach that the body that "is broken" and the blood that is shed, appeared as bread and wine, rather than literally appearing as the manifestly physical flesh and blood that was bruised and shed? 0
Where in Scripture is actual water referred to as blood, and thus poured out unto the Lord, and bread referred to as bread for the people of God, and the body of Christ as the church being bread? (2 Samuel 23:16-17; Num. 14:9)
Where in all of Scripture is spiritual life obtained by literally physically consuming anything? 0
Where in Acts and the apostles teaching in the NT (these being interpretive of the gospels) is spiritual life obtained by hearing and effectually believing the gospel of the grace of God? Acts 10:43; 15:7-9; Eph. 1:13)
Where from Acts onward in the NT is communion/partakers with the object of religious feasts and each other realized by literally consuming the flesh of the object of worship? 0
Where from Acts onward in the NT is communion/partakers with the object of religious feasts and each other realized by sharing a meal together ("feast of charity") in a way that effectually evidences remembrance? (1 Cor. 10,11 )
Where are distinctive Greek word for a separate class of sacerdotal believers (hiereus; archiereus; hieráteuma) distinctively used for NT pastors? 0
Where is a distinctive Greek word (hieráteuma) for a separate class of sacerdotal believers used for all believers? (1Pt. 2:5,9; Re 1:6; 5:10; 20:6).
Where from Acts onward in the NT are church pastors charged with or exampled uniquely conducting the Lord's supper and offering it up as a sacrifice for sins and dispensing it to the people as spiritual food? 0
Where from Acts onward in the NT are church pastors charged with or exampled as preaching the Word and feeding the flock with the Word which is called spiritual food ("milk," "meat") by which they are nourished? (Acts 20:28; 1Pt. 5:2 ;1Co. 3:22; 1Pt. 1:22; Heb. 5:12-14; 1 Timothy 4:6; Acts 20:32
Do you hear that? ... The ‘yesbuts’ are echoing forth! This you have given us is a faithful saying worthy of all acceptance. Thanks be to God.
You forgot, Roman Catholics don't NEED to find their doctrine/theology in Scripture. They believe their Pope and Magisterium are equal in authority to the Divinely-inspired word of God - as blasphemous as that sounds!
