[daniel1212]

his passage teaches us that all the saints are family of Christ and should be venerated as such; not just His relatives.

It, and the whole of the NT, also teaches us that all true believers are saints and part of the family of Christ, and treated as such, but not thought of above that which is written.

but not thought of above that which is written

The Holy Scripture has instances of venerating Mary (Luke 1:28, 11:27-8) and the Holy Apostles (Acts 19:12). It does not instances of venerating just any Christian. But as a private initiative, you can, of course: this is how saints are recognized.
