RW Schambach would recommend holiness... And then go on to say in one sermon, "There are a lot of devils in those Holiness churches." So it is important to stress the variety of Holiness taught here, which I believe this gathering is a good type of Holiness. In which this one is more of the 1800's variety of late Methodist Holiness, less the dress code of the times....

We Believe…
Scripture: The Bible is the divinely inspired word of God, providing authoritative guidance for every challenge and experience of life.
Salvation: All are under the penalty of sin, but God’s redemptive plan provides salvation for everyone who believes in Jesus Christ.
Sanctification: Sanctification is a second definite work of grace following salvation, which cleanses our hearts from the power of sin, and continues as a process of growing more Christ-like in everyday living.
The Holy Spirit: The Holy Spirit provides the sanctified believer the power to grow more like Christ in his daily walk.
And also has a reasonable dress code....
What Should I Wear? Our activities and worship services are held in open air ‘tabernacles’. So casual, modest attire is appropriate for all services and activities, particularly in and around the Main Tabernacle. Bathing suits should be worn only in the recreational areas.
Suggested for Women: Skirts, summer dresses, slacks; please avoid halter tops, shorts or backless dresses.
Suggested for Men: Slacks, jeans and khakis (suits and ties are not necessary).
