I do see in that letter specific things to avoid, one or two of which are hallmarks of Catholic sacramental ‘worship’.

I'm not sure that I understand your statement.
We worship God and God alone.
We pray to Him but we also pray to our dead family and friends.

We also pray to our patron saints or the saints who are particular in thing: St. Anthony of Padua is the patron saint of lost things. I HAVE prayed to him when something I lost was VERY important.
I don't ask that often but when I did he never let me down...and he helped me immediately.

Read the 15th chpter f Acts, read what ‘ seemed good to the Holy Spirit’ to avoid. Two of the namef things to avoid are central to Catholic sacramental worship. One of the hallmarks of your Eucharist is a direct disobedience to a command from The God.
