That is correct!
Mary shares in Christ’s redemptive work by her consent to God’s plan (Luke 1:38) and by her lifelong walk with Christ to the cross (Luke 2:35 and John 19) and her continued cooperation in heaven (Revelations 12). Who more than Mary participated in the sufferings of Christ (Colossians 1:24, Romans 8:17 et al.) by the "sword that would pierce her soul" (Luke 2:35)?
