Do we confess our sins like the Catholics (a priest)?
16 Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much.
28 You shall not make any cuttings in your flesh for the dead, nor tattoo any marks on you: I am the LORD.
1 Corinthians 4:7
7 For who makes you differ from another? And what do you have that you did not receive? Now if you did indeed receive it, why do you boast as if you had not received it?
