The statue of Risen Christ has features of the Late Gothic, thus it may be dated to the 16th century. It presents the triumphant Christ who rose from the grave. The robe (usually red) indicates his martyrdom and the flag is a symbol of victory over death. In the Middle Ages, sculptures were often used as props in dramatic liturgy. Statues of Risen Christ could be used during the Easter liturgy and the Ascension. The statue in Trzemeśnia was probably used in a Resurrection Procession, after which it was placed on the altar on the left, where it was located until the Ascension Day.
