Many (most?) churches encourage their members to tithe (let's call these churches A), and many have a biblical basis for it, e.g.:
- According to Reformed Theology, what is the doctrinal basis for belief in New Testament tithing?
- What is the biblical basis for the claim that Malachi 3:6-12's curse and blessings concerning tithing apply to the New Testament Church?
Similarly, many (most?) churches do NOT keep the sabbath (let's call these churches B), and many of them have a biblical basis for it as well, e.g.:
- What is the biblical basis for NOT keeping a literal physical Sabbath rest every seventh day?
- What is the biblical basis for believing that the Feast Days / Appointed Festivals / Holy Convocations are NOT morally binding for Christians today?
Now, I'm curious about those churches in the intersection between A and B, namely, those that encourage tithing AND do not keep the Sabbath at the same time. I'm struggling to see how this could possibly be a self-consistent position to hold. Both tithing and sabbath keeping were Old Testament laws, so if I were somehow forced to defend tithing as a law still binding on New Testament Christians, I'm unable to think of a single argument that wouldn't also lead to the unescapable conclusion that sabbath keeping is also binding. In my (possibly uninformed) opinion, if we have to tithe, then we have to keep the sabbath too.
