Some Catholics, sadly, seem to believe that the Fathers at the Second Vatican Council changed swathes of Church Teaching, even concerning central Teachings of the Church. Myths have grown up surrounding Vatican II. You may even have seen unsettling changes/modifications brought in and, having questioned them, been told that you must accept them as being in 'the spirit of Vatican II', whatever that may mean. The Council was Pastoral and not called to change the unchangeable (i.e. the Teaching that Christ commanded the Apostles to pass on in its entirety) but to remind us of the universal Vocation to Holiness; we are all, without exception, Pope, Bishops, Priests, Religious and Laity, called to 'do our bit'. Saint Josemaria Escrivá, Founder of Opus Dei, had already anticipated this call, clearly teaching that every Catholic, however 'insignificant' the world might consider them or their occupation, is called to live a holy life, whether in a 'high-profile' job such as a Cardinal, for instance or a somewhat less-regarded occupation such as a road-sweeper; the Grace of God, first sanctifying us in Baptism and ever there for the asking, enables us to attain this holiness.
Parents are crucial to this way of living. Through their love for God and, so, for one another, sustained by the Graces of the Sacrament of Matrimony, they form, through example, their children; they prepare, in this way, future Parents, Priests, Religious and Singles (just as much a Vocation) to be open to God's Call, to 'carry the torch' of Faith.
There is really no excuse for pleading ignorance of our role in the grand scheme of things. We are all, thank God, educated and literate. The Council Documents themselves are still readily available as are later documents, such as Veritatis Splendor' (the Splendour of Truth), from Saint Pope John Paul II; he wrote this to the world's Bishops in 1993, concerned that,"....certain fundamental truths of Catholic doctrine....risk(ed) being distorted or denied...". These and other documents make excellent discussion material. Generally these are freely available to read on-line. Try dipping into this huge library. Some real eye-openers here - a kind of Catholic 'Highway Code'!
