This heightened state of fear and trepidation typically takes hold of one’s heart following a remarkable experience (see the Commentary of Bishop Michael, part 2, p. 196).
St. Mark’s reference to the women’s silence is a distinctive element of his account, especially when contrasted with the descriptions provided by Matthew (28:8) and Luke (24:9), in which the women conveyed everything they had observed and heard to the Apostles. It would seem unnatural for them to refrain from sharing such a miraculous occurrence more than once; they were commanded by the angel to report everything (Mark 16:7). Additionally, St. Mark later asserts (v. 10) that the women, upon returning home, shared all this information with the apostles. Thus, they initially said nothing to anyone during their exit from the tomb. Since their flight from the tomb occurred before dawn, they might have encountered familiar individuals along the way, from whom their anxious expressions could have suggested something extraordinary. Hence, it is understandable that the women withheld their revelations until they were on their way back, without revealing what they had observed and experienced to acquaintances.
St. Mark further clarifies the rationale behind their silence, stating, "They were afraid." The fear and trembling that surged within the women as they exited the tomb rendered them mute until they reached the apostles. In the presence of Christ’s disciples, who shared their mindset, they had no cause for fear and were able to joyfully announce the good news to the Lord's disciples: Christ is risen.
