No.

Oh, you wanted me to elaborate more? I suppose I can.

Catholics can learn a great deal from Protestant Megachurches. In fact, Protestants can teach Catholics much in regards to defying Christ. Protestantism, which is a heresy against the Truth of Christ, can only teach Catholics error, falsities, and heresy. Even if a particular Protestant teaching is aligned with Catholic teaching, it is best to avoid it lest we become seduced into agreeing with error.

Protestants have been protesting the Catholic Church and her teachings and doctrines, which come from Christ, since the days of Martin Luther. It’s been a rather long protest and is motivated by human error, pride, and arrogance. These churches do not hold the truth and are man-made religions.

Seeing as the Catholic Church is the only Church Christ founded, we know it to have the fullness of the Truth. This Truth, which comes directly from God, gives assurance to this world that whatever the Church rules in the matters of faith and morals, has the backing of God. The Catholic Church is correct when it comes to worship, teaching, doctrine, and dogma.

Once Martin Luther broke away from the One True Church, he introduced error into all of his teachings, even those teachings he brought along from the Church. This is because he no longer accepted the fullness of Truth. Likewise, once Martin Luther broke away due to his disagreements with the Church’s teachings, thousands of other men and women like Luther have left either the Church or Luther to find their own “church”.

Protestant megachurches are so far down the broken branches of Christianity, they are hardly recognizably Christian. Rock and roll, charismaticism, hand waving, and long-drawn out sermons are the trademark of these groups. They use the name of Christ often to give a false confidence in their worship and to appear as if they hold the truth, but proclaim a false gospel by doing so. They have twisted the core of Genesis 1:26 and instead of conforming themselves and their wills to that of God’s, they have made a god in their own image, a god they can physically see every time they look in the mirror.

While even a broken clock is correct twice a day, I do not rely on a broken clock to tell me what the time is. If by happenstance the broken clock is correct, I do not know if it is correct, unless I have a working clock to compare. The same can be said with Protestantism. We only know if Protestant teaching is correct if we compare it with Catholic teaching, and if we need Catholic teaching to tell us if it is right or wrong, what good is the Protestant teaching?

The purpose of Christianity is to make as many members as possible, but not at the expense of undermining the Truth. When we undermine the Truth to gain members, we spread lies and false hope. Many people are attracted to the Truth and beauty of Catholicism. When listening to conversion stories, converts never become Catholic because of the “fun” or “giddiness” or the “welcoming”. But rather, they became Catholic because of the immense beauty and the Truth that Catholicism possesses which can be found in no other religion or creed on this Earth.

In reality, Catholics have far more they can teach Protestant megachurches on how to become more Christian. Being poised in matters of faith and morals, we can teach them how to properly worship God that is pleasing to Him through the Sacraments and devotions. Catholics can demonstrate to Protestants the beauty and Truth we possess in the Mass and our Liturgies, especially when celebrated according to the rubrics set up by our forefathers.

If we, as Catholics, continue this erroneous mentality that we can learn from Protestants to become better Catholics, we slip dangerously into the temptation of reducing the Church Christ founded into one of many churches. We reduce the effectiveness of the Truth being proclaimed because if we appear incorrect in one facet of faith, many will question if we are wrong in others. We risk the possibility of losing souls to error. Those souls who are outside the Church and outside of the state of grace at the moment of their death are likely to spend an eternity outside of God’s Kingdom, whether they chose to or not.
