“Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.” Mat 5:14-15
So here Christ says His Church will be visible.
“Careful to keep the unity of the Spirit in the bond of peace. One body and one Spirit: as you are called in one hope of your calling. One Lord, one faith, one baptism.” Eph 4:3-5
The Church is to be one, not many.
“And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.” Mat 6:18
Here Christ says his Church will not be destroyed.
“I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.” John 16:12-13
“But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and foundation of the truth.” 1Tim 3:15
Here Christ says, and Paul reaffirms, that the Church will always teach the TRUTH.
Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."Mat 28:18-20
Again, here Jesus assures us that He is always with us, to the very end.
So Christ says His Church will not be destroyed or fall away from him, that the Holy Spirit will guide the Church to always teach the Truth, and He will always be with us. The Church is much more than a collection of nice people who read a Bible and believe anything they want.
“But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and foundation of the truth.” 1Tim 3:15
“Here Christ says, and Paul reaffirms, that the Church will always teach the TRUTH.
Actually, Paul does not say what you claim. He says the Church is the pillar and foundation. There are many times in history where churches have gone into error.
“But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and foundation of the truth.” 1Tim 3:15
The house of God is the bodies of the believers. According to His Word, my body is His dwelling place.
I appreciate your passionate defense of the Catholic faith. I personally choose to assume a different perspective regarding the meaning of ‘church’. I align myself with Pope John Paul II who expressed:
“This affirmation of the Savior’s “uniqueness” derives from the Lord’s own words. He stated that he came “to give his own life in ransom for the many” (Mk 10:45), that is, for humanity, as St. Paul explains when he writes: “One died for all” (2 Cor 5:14; cf. Rom 5:18). Christ won universal salvation with the gift of his own life. No other mediator has been established by God as Savior. The unique value of the sacrifice of the cross must always be acknowledged in the destiny of every man. … For those, however, who have not received the Gospel proclamation, as I wrote in the Encyclical Redemptoris Missio, salvation is accessible in mysterious ways, inasmuch as divine grace is granted to them by virtue of Christ’s redeeming sacrifice, without external membership in the Church, but nonetheless always in relation to her (cf. RM 10). It is a mysterious relationship. It is mysterious for those who receive the grace, because they do not know the Church and sometimes even outwardly reject her. ... In order to take effect, saving grace requires acceptance, cooperation, a yes to the divine gift. This acceptance is, at least implicitly, oriented to Christ and the Church. ... Religions can exercise a positive influence on the destiny of those who belong to them and follow their guidance in a sincere spirit. ... The Church does not exist nor does she work for herself, but is at the service of a humanity called to divine sonship in Christ (cf. RM 19). She thus exercises an implicit mediation also with regard to those who do not know the Gospel.” (All Salvation Comes through Christ; General Audience — May 31, 1995)
Myself, as a person struggling to become a devout Catholic, cannot feel peace in my soul while holding the view that our Lords mercy is restricted solely for those who are Catholic. I believe that our God is much, much greater than that.
