The Hebrew Calendar

This ministry uses the standard Hebrew calendar to determine the dates of biblical Holy Days. After the Exodus, God established elders, priests and judges to administer civil and religious affairs within Israel. At first, they followed an arbitrary system based on direct observation to determine the start of months and years, but over time, Israel adopted a calculated calendar based on the best astronomical data available. All calendar systems need to be adjusted over time, but certain individuals want to modify the Hebrew calendar on their own without proper authorization. We will follow the standard Hebrew calendar until a new Sanhedrin convenes, or Jesus Christ returns, and updates the current system.

Religious Titles

This ministry avoids the use of certain terms as religious titles. Jesus taught His disciples not to call one another “Rabbi” (Teacher), “Father” or “Master” in a religious sense because there is only one Person who rightly holds those titles (Matt 23:8-11). Moreover, we avoid related terms such as “Reverend,” “your Holiness” or “your Grace” for the same reason. God alone is worthy of such lofty titles.

Charismatic Gifts

Many people today claim to have charismatic gifts such as miraculous healing, prophetic revelation and speaking in tongues (foreign languages), but their dubious record to date suggests otherwise. Therefore, this ministry will apply careful, biblical tests to anyone in our fellowship groups claiming to have such gifts (e.g., Deut 13, 18, Isa 8:20, 1John 4:1). Candidates will be expected to (1) have a reputation for godly behavior, (2) teach what agrees with Scripture and (3) demonstrate a verifiable miracle as evidence of divine authorization.

The Sacred Name Controversy

This ministry does not require or forbid the use of terms like “Yahweh,” “Yeshua,” “God” or “Jesus,” but we do discourage the use of the term “Jehovah” since it is not a legitimate word. There is no biblical prohibition against speaking God’s sacred name, and it is self-evident that ancient Israelites commonly did so. Some groups argue endlessly about the precise pronunciation of Hebrew names as if this makes any difference to the God who knows all of our thoughts.The important point is to treat God’s name with respect no matter which language we use.

Images of Jesus

We do not use images of Jesus in print or video content for several important reasons. First, there are no reliable descriptions of Jesus, and the most common depictions are certainly inaccurate and misleading. Second, people use such images to disobey the spirit and letter of God’s law against idolatry (Deut 4:11-19). Third, these images tend to focus on the death of Jesus which distracts people from thinking of Him as the risen and glorified Lord (cf. Rev 1:9-18).

Biblical Holy Days

We support the growing recognition among Christians that the seventh-day Sabbath and annual festivals listed in Leviticus 23 are a tangible proclamation of God's plan of salvation for humanity and that they constitute the proper basis for sanctified worship by God's people.


We also offer opportunities to observe the biblical holy days while touring the Holy Land with other Sabbath-keeping Christians. The trip is physically demanding, so you must be able to tolerate heat and climb steps or hills. But, the view is worth the climb. Trips vary based on level of interest and must be planned well in advance.
