"O Come, Let Us Adore Him" is a Christmas Eve candlelight service poster for St. Mark's Parish, painted in a vintage winter-night style. Cream serif lettering sits above a navy starry sky, a snowy stone chapel with glowing windows and a lit candle. Swap in your own parish name, service time and headline to make a church event poster.

Create a finished 3:4 portrait Christmas card front for St. Mark's Parish, designed to read clearly at phone-thumbnail size and print cleanly at 5×7 inches. Keep all lettering and key details comfortably inside a generous safe margin. Set exactly these three lines of text, with perfect spelling and punctuation: the large, dominant greeting “O Come, Let Us Adore Him”; below it, “St. Mark's Parish”; and at the bottom, “Christmas Eve candlelight service at 11 PM”. Do not add any other text. Use a reverent, intimate winter-night illustration: a small stone church with a warmly lit window stands in fresh snow beneath a deep midnight-blue sky; one tall lit candle in the foreground casts a steady amber glow across the snow. The church and single candle are the only major motifs. Keep the scene painterly and finely textured, like a carefully printed vintage Christmas card, with subtle paper grain and delicate engraved detail, not photorealistic. Warm candlelight softly illuminates the nearby snow while distant snow remains cool blue; use only a few restrained gold star-like flecks in the sky. Place the greeting in the upper portion, centered and prominent, on a quiet dark-sky area with strong contrast. Letter it in refined, high-contrast ivory serif capitals and lowercase, with graceful tapered serifs, open counters, generous spacing, and a subtle warm-gold edge catching the candlelight. Keep the words large and crisp, arranged over two balanced lines if needed. Place the church and candle in the broad middle illustration zone; candle in the foreground, church slightly behind it, both clearly recognizable and unobscured. Center “St. Mark's Parish” beneath the illustration in smaller but readable ivory serif type. Set the service line at the bottom in a clean, compact serif, still comfortably legible at print size. Use balanced spacing, a thin understated antique-gold rule near the lower text, and no border ornament that competes with the greeting. Palette: midnight navy, snowy ivory, muted evergreen, warm amber, restrained antique gold. Quiet, faithful, welcoming, polished and unmistakably a Christmas Eve candlelight card.
