…we always need to be on guard against lukewarmness, or the apathetic spirit which seems to characterize the Church today. We are not immune, any of us, from the crafts and assaults of the devil. If we do not constantly return in faith to the One who died and rose for us, then we could very well be the one who is told by the Lord, “Depart from me, I never knew you, you worker of lawlessness.” Yes! Even though you are baptized; even though you hear the Word outwardly, even though you come to the Sacrament.
It happened with many of the Jews. They were the invited guests, the ones that God had initially called to the wedding of His Son. Like the servants in the Parable, the prophets went to them and told them that the feast was ready, that it was time for their Savior to come. And see how many disbelieved! They mistreated the prophets and even killed them. And yet, they belonged in an outward sense to the true Church. They offered the right sacrifices; they went to the synagogue, but, as the King says in the Parable, they were not worthy.
Then came John the Baptist, and the disciples, and Jesus Himself. All of them ignored by the majority of the so-called invited guests. “They paid no attention and went off, one to his farm, another to his business, while the rest seized his servants, treated them shamefully, and killed them.”
These were not people outside of the visible fellowship of the Church, dear friends. These were people like you—people who were recognized by their friends and neighbors as the people of God! The point of all this is this—do not assume that just because you are a Christian in name that your name is written in the book of Life.
At the end of the day, what matters is where your faith is. If you are sorry for your sins, and trust in the merits of Christ, then you have the proper attire. Are you serious about ridding yourself of sin, or how to become righteous and attain salvation? Then you have the wedding garment of salvation. You are worthy guests at the Lord’s Table, where we have here a foretaste of the wedding feast to come. You are covered by the righteousness of Christ, and you are justified in God’s sight through faith in Christ’s suffering, death, and resurrection.
