It’s not that confusing. Take fasting for example. The sin is in not obeying the precept of the Church regarding fasting. The specifics of that precept may change and one’s behavior can change to obey the current rules.Honestly, you’ve lost me, kind of. How can something be sinful at one point, then not at another?
Attending Mass on Holy Days is also a precept of the Church. Which days have the obligation is different in different countries, as determined by the conference of bishops. The duty is to obey your own bishops; sinful if you do not.
Attending Protestant services is one of those things that is a change in the “how” a teaching is implemented. The underlying teaching is that Catholics must avoid attaching themselves to non-Catholic communities and to avoid any behavior that would give scandal. In decades past, the prudential way to do that was to not allow Catholics to even attend Protestant services without dispensation. Today, attending is not strictly prohibited but the caution about attaching still exists. The “how” of that is that Catholics do not receive Communion at Protestant services, they can’t become members of Protestant congregations and, of course, they can’t let attendance at Protestant services interfere with their Sunday obligation at Catholic Mass.
Without getting too off topic, this is a charge often lobbied at Catholics regarding eating meat on Friday. Why was it a sin in the 1950s to eat meat on a Friday (not in Lent) but it’s not a sin today? The answer is that in the 1950s, the precepts regarding fasting included all Fridays, now it only includes the Fridays in Lent. The sin was on of disobedience, not of eating a steak.
