I would like to focus on the parable of today’s Mass and explain what it means in relation to our salvation. The parable tells the story of a day of hiring.“Day” in this parable, as far as the story goes, refers only to a 12 hour period, or that part of the day that is in daylight. But the Fathers have understood this 12 hour period to be a symbol of two different longer periods of time, namely, the time before Christ, and the duration of our life.If we take the “day” of the parable as the time before Christ, following Origen, we can understand the various calls at the different hours as missions given to the great figures of the Old Testament by God to accomplish His work. They are to work in His vineyard, which represents the field of labor in which a person is living for Heaven and is trying to get as many people as possible to follow him on that path to Heaven.The second sense of the “day” is the span of the lifetime of each individual. Each person is called to work for the kingdom of Heaven, that is, for his own salvation.Some are fortunate enough to be called in the morning of their life, by being born into a Catholic family. Others convert as teenagers, others as young adults, others as mature men, others as old men. For each of these is reserved the denarius of salvation or eternal life.But there is a condition. Each one must remain working in the vineyard, once they are called. It is only when evening comes that the payment is given. Those who are not present at the evening, or the end of their life, will not receive payment from the householder. We must remain in the state of grace if we are to receive the reward of Heaven.
