This is part of the explanation of beliefs from the site of an Apostolic Church in TX. At least since they teach that
Deut. 22:5 (part of the Old Covenant) is applicable to us today, they also take another requirement of the law and apply it to today
Holiness
The word says and makes it VERY CLEAR: "Without HOLINESS it is IMPOSSIBLE to please Elohim."!
After we are saved from sin, we are commanded, "Go, and sin no more" (
John 8:11).
We are commanded to live soberly, righteously, and godly (Holy) in this present world (
Titus 2:12) and warned that without holiness no one shall see YHWH (
Hebrews 12:14).
We must present ourselves as holy unto YHWH (
Romans 12:1), cleanse ourselves from all filthiness of the flesh and spirit (
II Corinthians 7:1), and separate ourselves from all worldliness (
James 4:4).
If the righteous scarcely be saved, where shall the ungodly and the sinner appear? (
I Peter 4:18).
No one can live a holy life by his own power, but only through the Holy Spirit. "Ye shall receive power, after that the Holy Ghost is come upon you AND YOU SHALL BE WITNESSES" (
Acts 1:8)
Holiness is MORE than an inward condition. It is making clean the INSIDE of the cup AND THE OUTSIDE as well. It is "coming out from the world and being separate". The word teaches MODESTY in dress as well as in all other things.
DID YOU KNOW that the Word teaches that a woman should NOT "wear that which pertaineth to a man and neither should a man put on a woman's garment", that her hair is her glory, that she should NOT outwardly adorn herself, that she should be shame faced and not wear costly array?--that a woman should NOT pray without her head being covered and that she should remain silent in the church?
DID YOU KNOW that man was created in the very image of God? That the Word says that a man should NOT "marr the corners of his BEARD"? Since every single man was created in God's image and every single man grows a BEARD and facial hair by the time that he reaches puberty his beard was given by God as a separation of the sexes it would displease YHWH for him to try to shave it off?
DID YOU KNOW that WE are supposed to "come out from the world and be ye separate" and that we are to be a PECULIAR people?
