Moreover, in the Gospel of Matthew, there is guidance for the apostles to select the homes they enter, thereby avoiding unnecessary changes in residence that would breach the rules of hospitality. However, it is important to note that the responsibility for choosing guests does not rest with the host; otherwise, such discretion would undermine the very essence of hospitality.
While the call for the noble practice of hospitality is commendable in a literal context, its interpretation as a spiritual commandment bears profound sacramental significance. When selecting a home, one seeks a worthy host. This implicitly suggests a preference for the Church and Christ. What dwelling is more fitting for the apostles than the sacred Church? And who deserves our utmost devotion if not Christ, who humbly washes the feet of His guests? Christ does not permit those welcomed into His dwelling to remain dirty; He cleanses them of their past life, preparing them for eternity. He is the ultimate Master, one who should never be forsaken or exchanged for another. To Him we should turn and say, “Lord, to whom shall we go? You have the words of eternal life, and we have believed” (John 6:68-69).
Consider Peter, who embodies the fulfillment of divine commands and welcomed others, earning a place in heavenly sanctification. Therefore, the primary aspect to reflect on is the faith of the Church: if Christ resides within, it is certainly the right choice! However, if those present are non-believers or if a heretical teacher dishonors the establishment, one must distance themselves from heretics and depart from such a gathering. It is essential to shake off the dust from one's feet to avoid allowing the soul to become contaminated by the barrenness of disbelief, akin to dry, sandy earth.
A gospel preacher must bear the weaknesses of the faithful and discard their empty actions as one would brush away dust, as stated, “Who is weak, and I am not weak?” (2 Corinthians 11:29). If there exists a community that rejects faith and lacks a foundation in apostolic teachings, it must be left behind to prevent the spread of unbelief. The Apostle makes this point clear: “After one admonition to the heretic, turn away from him” (Titus 3:10).
