We then who are strong ought to bear with the scruples of the weak, and not to please ourselves. Let each of us please his neighbor for his good, leading to edification. For even Christ did not please Himself; but as it is written, “The reproaches of those who reproached You fell on Me.” For whatever things were written before were written for our learning, that we through the patience and comfort of the Scriptures might have hope. Now may the God of patience and comfort grant you to be like-minded toward one another, according to Christ Jesus, that you may with one mind and one mouth glorify the God and Father of our Lord Jesus Christ. Therefore receive one another, just as Christ also received us, to the glory of God. Now I say that Jesus Christ has become a servant to the circumcision for the truth of God, to confirm the promises made to the fathers, and that the Gentiles might glorify God for His mercy, as it is written: “For this reason I will confess to You among the Gentiles, And sing to Your name.” And again he says: “Rejoice, O Gentiles, with His people!” And again: “Praise the Lord , all you Gentiles! Laud Him, all you peoples!” And again, Isaiah says: “There shall be a root of Jesse; And He who shall rise to reign over the Gentiles, In Him the Gentiles shall hope.” Now may the God of hope fill you with all joy and peace in believing, that you may abound in hope by the power of the Holy Spirit.
Romans 15:1-13 NKJV
And it came to pass after three days that Paul called the leaders of the Jews together. So when they had come together, he said to them: “Men and brethren, though I have done nothing against our people or the customs of our fathers, yet I was delivered as a prisoner from Jerusalem into the hands of the Romans, who, when they had examined me, wanted to let me go, because there was no cause for putting me to death. But when the Jews spoke against it, I was compelled to appeal to Caesar, not that I had anything of which to accuse my nation. For this reason therefore I have called for you, to see you and speak with you, because for the hope of Israel I am bound with this chain.” Then they said to him, “We neither received letters from Judea concerning you, nor have any of the brethren who came reported or spoken any evil of you. But we desire to hear from you what you think; for concerning this sect, we know that it is spoken against everywhere.” So when they had appointed him a day, many came to him at his lodging, to whom he explained and solemnly testified of the kingdom of God, persuading them concerning Jesus from both the Law of Moses and the Prophets, from morning till evening. And some were persuaded by the things which were spoken, and some disbelieved. So when they did not agree among themselves, they departed after Paul had said one word: “The Holy Spirit spoke rightly through Isaiah the prophet to our fathers, saying, ‘Go to this people and say: “Hearing you will hear, and shall not understand; And seeing you will see, and not perceive; For the hearts of this people have grown dull. Their ears are hard of hearing, And their eyes they have closed, Lest they should see with their eyes and hear with their ears, Lest they should understand with their hearts and turn, So that I should heal them.” ’ “Therefore let it be known to you that the salvation of God has been sent to the Gentiles, and they will hear it!” And when he had said these words, the Jews departed and had a great dispute among themselves. Then Paul dwelt two whole years in his own rented house, and received all who came to him, preaching the kingdom of God and teaching the things which concern the Lord Jesus Christ with all confidence, no one forbidding him. Acts 28:17-31 NKJV
Now an angel of the Lord spoke to Philip, saying, “Arise and go toward the south along the road which goes down from Jerusalem to Gaza.” This is desert. So he arose and went. And behold, a man of Ethiopia, a eunuch of great authority under Candace the queen of the Ethiopians, who had charge of all her treasury, and had come to Jerusalem to worship, was returning. And sitting in his chariot, he was reading Isaiah the prophet. Then the Spirit said to Philip, “Go near and overtake this chariot.” So Philip ran to him, and heard him reading the prophet Isaiah, and said, “Do you understand what you are reading?” And he said, “How can I, unless someone guides me?” And he asked Philip to come up and sit with him. The place in the Scripture which he read was this: “He was led as a sheep to the slaughter; And as a lamb before its shearer is silent, So He opened not His mouth. In His humiliation His justice was taken away, And who will declare His generation? For His life is taken from the earth.” So the eunuch answered Philip and said, “I ask you, of whom does the prophet say this, of himself or of some other man?” Then Philip opened his mouth, and beginning at this Scripture, preached Jesus to him. Now as they went down the road, they came to some water. And the eunuch said, “See, here is water. What hinders me from being baptized?” Then Philip said, “If you believe with all your heart, you may.” And he answered and said, “I believe that Jesus Christ is the Son of God.” So he commanded the chariot to stand still. And both Philip and the eunuch went down into the water, and he baptized him. Now when they came up out of the water, the Spirit of the Lord caught Philip away, so that the eunuch saw him no more; and he went on his way rejoicing. But Philip was found at Azotus. And passing through, he preached in all the cities till he came to Caesarea. Acts 8:26-40 NKJV
Then the scribes and Pharisees who were from Jerusalem came to Jesus, saying, “Why do Your disciples transgress the tradition of the elders? For they do not wash their hands when they eat bread.” He answered and said to them, “Why do you also transgress the commandment of God because of your tradition? For God commanded, saying, ‘Honor your father and your mother’ ; and, ‘He who curses father or mother, let him be put to death.’ But you say, ‘Whoever says to his father or mother, “Whatever profit you might have received from me is a gift to God ”— then he need not honor his father or mother.’ Thus you have made the commandment of God of no effect by your tradition. Hypocrites! Well did Isaiah prophesy about you, saying: ‘These people draw near to Me with their mouth, And honor Me with their lips, But their heart is far from Me. And in vain they worship Me, Teaching as doctrines the commandments of men.’ ” When He had called the multitude to Himself, He said to them, “Hear and understand: Not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man.” Then His disciples came and said to Him, “Do You know that the Pharisees were offended when they heard this saying?” But He answered and said, “Every plant which My heavenly Father has not planted will be uprooted. Let them alone. They are blind leaders of the blind. And if the blind leads the blind, both will fall into a ditch.” Then Peter answered and said to Him, “Explain this parable to us.” So Jesus said, “Are you also still without understanding? Do you not yet understand that whatever enters the mouth goes into the stomach and is eliminated? But those things which proceed out of the mouth come from the heart, and they defile a man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies. These are the things which defile a man, but to eat with unwashed hands does not defile a man.” Matthew 15:1-20 NKJV
