Catholics: Don't let your guard down and allow non-denominational Evangelical Christians (or even other Catholics!) to persuade you into thinking we are all on the same path because we all follow Christ and believe in His Word -- as if we are merely different brands of the same product.
We are not the same.
If we were the same, they would not wholeheartedly reject the source and summit of the Faith -- the Eucharist -- even believing Eucharistic adoration is idolatry.
If we were the same, they would not reject the basics of the Faith, like the answer to sin: sacramental baptism and confession.
If we were the same, they would not reject Saint Paul's explicit command to hold fast to oral Tradition.
Recognize that their foundational beliefs come straight from the Protestant heresy. Yes, Protestantism is a serious and dangerous heresy.
Indulging in false ecumenism is to perpetuate a lie, and it serves neither the truth nor your non-Catholic friends. And it's a scandalous example to fellow Catholics, with the potential to weaken their faith.
Catholics must speak the truth in love.
