I was brought up RC and we were strongly discouraged from working on Sunday, in fact as a non-Catholic doing work for some devout Catholics I was not permitted or strongly discouraged from doing work for them on Sundays.
In a certain sense I get this, honoring various OT Sabbaths was commanded ny the ten commandments. So ascribing a day or days of rest (not any particular day per Rom 14) to the NT Christian makes sense to me. I think of it as fulfilling a placeholder of the OT commandment, yet understanding Christ is our Sabbath Rest. Similarly honoring those God has placed over you has NT life application as well. Whether it be your teachers, bosses, your civic leaders, pastors, elders, parents etc, these are all being fulfilled by extension, as the placeholder for honoring your mother and father under the old [OT].
