This distinction between adoration vs veneration should be easily resolved. What do the Apostles say in Scripture should be offered to Mary, veneration or adoration?
That it is false can be easily proven by listing a few of the bazillion things which are not made explicit in Scripture:
It is un-Biblical to assume that Scripture alone can resolve religious questions, because the Bible itself refers to sources of Apostolic truth beyond what is in the written text. For instance, the Apostles' example:
Philippians 3:17
Join with others in being imitators of me, brothers, and observe those who thus conduct themselves according to the model you have in us.
Or here,
2 Thessalonians 2:15Or here, where Jesus says the Church itself has the authority to make rulings:
Therefore, brothers, stand firm and hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours.2 Thessalonians 3:6
We instruct you, brothers, in the name of Our Lord Jesus Christ, to shun any brother who conducts himself in a disorderly way and not according to the tradition they received from us.
Matthew 18:17
If he refuses to listen even to the Church, then treat him as you would a Gentile or a tax collector.1 Timothy 3:15
The church of the living God, the pillar and foundation of truth.
OK?
But let's look to God's Word in the Old Testament for many an example of holy veneration of human persons, which is not the same as adoration due to God alone. This is something that wonderfully permeates Old Testament culture.
So, veneration? Totally Biblical.
