'Relating' in the Bible

Wherefore it behoved him in all things to be made like to his brethren, that he might be a merciful and faithful high priest in things relating to God, to make propitiation for the sins of the people;

For every high priest selected from among men is appointed to officiate on their behalf in matters relating to God, that is, to offer gifts and sacrifices for sins.

But in your case, dear friends, even though we speak like this, we are convinced of better things relating to salvation.
