A secularized Catholic is someone who claims to be a Catholic Christian, who might even attend Mass on a regular basis, but who believes the teachings of secular society over the teachings of the Church. The true test of faith is found when the Church has a teaching that is irreconcilable with the majority opinion in society.

[Exodus]
{23:2} You shall not follow the crowd in doing evil. Neither shall you go astray in judgment, by agreeing with the majority opinion, apart from the truth.

Secular Catholics often attribute certain ideas to Jesus, when in fact those ideas are from sinful secular society. For example, a secular Catholic will claim that Jesus was inclusive. Not so.

[Matthew]
{10:32} Therefore, everyone who acknowledges me before men, I also will acknowledge before my Father, who is in heaven.
{10:33} But whoever will have denied me before men, I also will deny before my Father, who is in heaven.
{10:34} Do not think that I came to send peace upon the earth. I came, not to send peace, but the sword.
{10:35} For I came to divide a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law.
{10:36} And the enemies of a man will be those of his own household.
{10:37} Whoever loves father or mother more than me is not worthy of me. And whoever loves son or daughter above me is not worthy of me.
{10:38} And whoever does not take up his cross, and follow me is not worthy of me.
{10:39} Whoever finds his life, will lose it. And whoever will have lost his life because of me, shall find it.

Secular Catholics do not believe that abortion is always wrong; they use contraception and have sexual relations outside of marriage; they think that the Church’s teaching against gay marriage is antiquated or intolerant; they do not get their ideas from the Saints, Fathers, and Doctors of the Church, nor from Sacred Scripture, nor from the Magisterium. They reject any teaching of the Magisterium that is not in accord with their own understanding, and that understanding is based on secular society.

Are you a secular Catholic? Compare your beliefs to those of the Church and of secular society. When there is a conflict between Church teachings and the majority opinion of the culture in which you live, which idea do you believe?
