IFCA International affirms the observance of Christmas and Easter as commemorations of Christ's incarnation and resurrection respectively. Unlike some Reformed traditions that restrict worship observances to those explicitly commanded in Scripture, the IFCA permits and encourages the celebration of these holidays. Christmas celebrates the birth of Christ, the divine Son entering human history; Easter celebrates Christ's resurrection, the foundation of Christian faith and redemption.

These observances are not considered binding or necessary to salvation, nor are they viewed as having inherent sacramental significance. Rather, they are occasions for focused reflection on central Christian truths, for special worship gatherings, and for teaching Scripture to believers. Churches may hold special services, nativity presentations, or resurrection celebrations that enhance worship and instruction without imposing legalistic requirements.

The IFCA does not prohibit the celebration of holidays. While recognizing some commercial and cultural accretions that may accompany Christmas and Easter, the IFCA sees value in set times of worship and reflection. Congregations may vary in how they observe these holidays — some with elaborate celebrations, others with simple observances — reflecting congregational autonomy. The principle is that holidays serve faith and worship, not that they are forbidden or legally required.
