False doctrines aside, you should leave the Catholic church simply because scripture admonishes the church to be of one mind. So, I encourage you to attend a church that matches your convictions, because to do otherwise is to violate scripture.
Romans 12:16 Be of the same mind one toward another.....
Romans 15:5 Now the God of patience and consolation grant you to be likeminded one toward another according to Christ Jesus: 15:6 That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.
2 Corinthians 13:11 Finally, brethren, farewell. Be perfect, be of good comfort, be of one mind, live in peace; and the God of love and peace shall be with you.
Philippians 1:27 Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;
Philippians 2:2 Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind.
1 Peter 3:8 Finally, be ye all of one mind, having compassion one of another, love as brethren, be pitiful, be courteous:
Do not be fooled by SteveR's defense of John Y. John has repeatedly made it clear many, many times that not only does he not have any desire or obligation to attend a biblically sound church, but even if he did, he would sit in the back, never talk to anyone and leave as soon as the service is over. He says he is a "lone maverick" when it comes to fellowship, and feels that its not necessary. And some how this is Christian to SteveR.
Alas, how many there are today who imagine that if they have "faith", it is sure to be well with them at the end, even though they are not holy. Under the pretense of honoring faith, Satan, as an angel of light, has deceived, and is still deceiving, multitudes of souls (2Cor 11:14). But when their faith is examined and tested, what is it worth? Nothing at all so far as ensuring entrance to heaven is concerned; it is a powerless, lifeless, and fruitless thing! It is no better than that faith which the demons have (James 2:19). The faith of Gods elect is unto "the acknowledging of the truth which is after godliness" (Titus 1:1). Saving faith is a "most holy faith" (Jude 20): it is a faith that purifieth the heart (Acts 15:9); it is a faith that worketh by love (Galatians 5:6); it is a faith that overcometh the world (1John 5:4); it is a faith that bringeth forth all manner of good works (Hebrews 11).

In my opinion, the unbiblical idea that Christ rejecing Jews in Israel are Gods people has caused more problems for the church than ISIS, as it has led to dispensationalism and other absurd beleifs. Ive even heard some church leaders and Christian speakers say that ISIS isnt worth putting boots on the ground, but if they attack Israel we need to go in there no holds barred and anilhilate them. Thats just ridiculous. But, I know we disagree on this issue, so lets agree to disagree.
