SAC'RAMENT, n. [L. sacramentum, an oath, from sacer, sacred.]
1. Among ancient christian writers, a mystery. [Not in use.]
2. An oath; a ceremony producing an obligation; but not used in this general sense.
3. In present usage, an
outward and visible sign of inward and spiritual grace; or more particularly, a solemn religious ceremony enjoined by Christ, the head of the christian church, to be observed by his followers,
by which their special relation to him is created,

or their obligations to him renewed and ratified. Thus baptism is called a sacrament, for by it persons are separated from the world, brought into Christ's visible church, and laid under particular obligations to obey his precepts. The eucharist or communion of the Lord's supper, is also a sacrament, for by commemorating the death and dying love of Christ, christians avow their special relation to him, and renew their obligations to be faithful to their divine Master. When we use sacrament without any qualifying word, we mean by it,
4. The eucharist or Lord's supper.
SAC'RAMENT, v.t. To bind by an oath. [Not used.]
What it all boils down to is that the way sacrament is used is not (entirely

) the same way that it used to be used.
The main reason I don’t like the term sacrament is because it is commonly used to describe the giving of grace instead of an action done as a result of having been given grace.
Other than the common usage, I wouldn’t have any problem with using the word. I allow for it in conversation often without interrupting depending on the subject matter being discussed. It isn’t always worth the distraction from the conversation.
