Here is a statement on justification from Walter Maier, submitted to Ft Wayne in January 1981. How could Jesus have been "acquitted" of the sins imputed to Him? In legal language, it seems confusing to me that Jesus paid for our sins but that He was also acquitted. How can you acquit someone after they've paid the price of the charges laid against them (in this case, charges brought against Christ by imputation only and not by actual committed sin)
When the Lord Jesus was “justified” (I Timothy 3:16) in His resurrection and exaltation, God acquitted Him not of sins of His own, but of all the sins of mankind, which as the Lamb of God He had been bearing (John 1:29), and by the imputation of which He had been “made...to be sin for us” (II Corinthians 5:21), indeed, “made a curse for us” (Galatians 3:13). In this sense, the justification of Jesus was the justification of those whose sins He bore. The treasure of justification or forgiveness gained by Christ for all mankind is truly offered, given, and distributed in and through the Gospel and sacraments of Christ. Faith alone can receive this treasure offered in the Gospel, and this faith itself is entirely a gracious gift and creation of God through the means of grace. Faith adds nothing to God’s forgiveness in Christ offered in the Gospel, but only receives it. Thus, “He that believeth on the Son hath everlasting life: and He that believeth not the Son, shall not see life; but the wrath of God abideth on Him” (John 3:30)
