Mission
The mission of Hallelujah Oratorio Society is to promote and raise the standard of church music in the Asian region. Through its concerts, musical training, products and publications, HOS cultivates and trains talents in church music.

Objective
The objective is to encourage and challenge Christians to serve in the Church Music Ministry, with the aim of raising the standard and quality of church music amongst the churches.

Theme 2008-2012
AS WITH ONE VOICE
“All the Levites who were musicians…and their sons and relatives – stood on the east side of the alter, dressed in fine linen and playing cymbals, harps and lyres…The trumpeters and singers joined in unison, as with one voice, to give praise and thanks to the Lord…” 2 Chronicles 5:12-13a, NIV

This verse inspired and gave insights to the ministry of HOS henceforth. For to serve in the church music ministry is to be identified with the Levitical priesthood, performing the role with skilled craftsmanship and efficiency, thereby building generations of singers and its supportive community. “As with one voice” is the testimony of this commitment.

Our prayer
May our Lord be so pleased that “the temple of the Lord was filled with a cloud, and the priests could not perform their service because of the cloud, for the glory of the Lord filled the temple of God.” (2 Chronicles 5:14, NIV) Amen.

宗旨
哈利路亚圣乐社以促进亚洲区域圣乐普及化及提高圣乐水平为宗旨，透过举办音乐会、圣乐训练、圣乐刊物及产品，培育优秀的圣乐人才。

目标
透过哈利路亚圣乐社的事工激励并挑战基督徒委身于圣乐事奉，积极成为教会圣乐事工的支持与动力。

主题
齐声合韵
“全体负责歌唱的利未人…，以及他们的儿子和亲族，都穿着细麻布的衣服，站在祭坛的东边，敲钹、鼓瑟、弹琴；…吹号和歌唱的都一致同声地赞美称谢耶和华。…”历代志下5:12-13上，新译本

此经文带给圣乐社启发与洞见，以至成为圣乐社今后的事工方向。委身于圣乐事工相等于扮演利未人的祭司角色，以精湛的技艺和效率执行职责，从而传承歌唱一族与建立支柱群体。“齐声合韵”就是这种委身的见证。

祈求
愿主喜悦我们如此行，以至“云彩充满那殿，就是耶和华的殿。由于那云彩的缘故，祭司都不能侍立供职，因为 神的殿充满了耶和华的荣光。”（历代志下5:14，新译本。）阿们。
