Grrr!
Is this entirely fair? I have Rheumatoid and Osteo arthritis, and sometimes I have a lot of pain and stiffness, and sometimes not. There are flare-ups and remissions. If somebody in the parish put me under hostile surveillance and recorded inconsistencies in my sitting, standing and kneeling, I'd suspect there was an unkind bias on the part of the critic.
I can think of substantive things we *have* to criticize Pope Francis for, especially and above all trying to introduce formal heresy into the Ordinary Magisterium via that "Amorphous Laetitia" material that was just published (Dec 2017) over Parolin's signature in the AAS.
That's what we should concentrate on. Not prayer-posture issues.
Join me, please, in praying for old Tio Jorge's well-being, conversion, redemption. Just what we should want, also, for ourselves.
