The wall of fine linen around the tabernacle presented a barrier to those who were not 'righteous before God' making sure that they would not have access to the courtyard. This teaches us that the thing that separates those inside the Church from those outside, is not a higher level of human righteousness, but that those inside are clothed with the righteousness of Christ.

When speaking of being "clothed with the righteousness of Christ, the Church teaches that the scriptures say that we are justified by the remission of our sins,and also sanctified and renewed in the inner man.
