What did the Worshipful Master instruct the Senior Warden after the obligation?

The instruction given by the Worshipful Master to the Senior Warden after the obligation relates directly to the theme of initiation and the significance of the cable tow. The cable tow symbolizes the bonds of responsibility and connection one has within the fraternity. Releasing the candidate from the cable tow indicates that they are now free from the restraints of prior obligations and are officially welcomed into the fraternity as a Fellow Craft. This action not only signifies the completion of their initiation but also marks the beginning of their journey in the Masonic tradition.

This understanding is pivotal in Freemasonry, as it emphasizes personal growth and commitment to the ideals and values taught within the lodge. The other options, while related to lodge activities and duties, do not directly reflect the immediate actions required after the obligation in the context of welcoming a new member. Preparing a feast, introducing the candidate, or teaching the next degree occur later in the process and are part of the broader aspects of lodge activities and education.
