Depending on the translation used, it either says "this do" or "do this".
Baptism and The Lord's Supper are symbols of the death, burial, and resurrection; and of the breaking of His body and the spilling of His blood. Both symbolic.
They are not merely symbolic, as Scripture clearly demonstrates.
1 Peter 3:21 There is also an antitype which now saves us -- baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ
1 Cor 11:27 Therefore whoever eats this bread or drinks [this] cup of the Lord in an unworthy manner will be guilty of the body and blood of the Lord.
KJV: 1Peter 3:21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
an-teet'-oo-pon Neuter of a compound of G473 and G5179; corresponding (antitype), that is, a representative, counterpart: - (like) figure (whereunto).
